>iPhone Complains & Problems

>Singapore - With every new firmware updates for the iPhone coming out faster and faster, third party application programmers have to keep updating and patching their programs. Bugs and problems continue to plague the iPhone users with different firmware updates for unlocked iPhones and it sometimes give a bad impression to the high expectations of the iPhone. Worse is that users didn’t know that they do not have to put up with such iPhone bugs and problems. They are stuck with such iPhone bugs and problems because the iPhone sellers simply don’t care. Some users are stuck with damaged and spoilt iPhones, feeling they have bought an iPhone bargain but in the end, because they can’t use the phones, turn out to be a sour lemon instead.

A check on the Internet revealed some of the many frustrating iPhone users due to the iPhone bugs and problems. Despite some iPhone sellers selling their unlocked iPhones at a cheaper price, but with so many problems and complains and half working iPhones, the users are just not getting any value out of their iPhones. Many of the iPhone sellers simply don’t care anything else, they made sweet promises but just don’t deliver.

However, a Singaporean company,, have been highly recommended by the iPhone buyers because of their technical knowledge of the iPhones and the after sales service rendered to the customers. In a couple of cases, iPhone-Singapore has swapped hardware damaged iPhones for brand new sets to the customers because of their warranty coverage. It’s a case by case basis. Such exchange would definitely not be possible when purchasing the iPhones from other sellers. In the case of Mr Kevin Omre from Bahrain, iPhone-Singapore even compensated him for the shipping cost to get his iPhone repaired. Customers from iPhone-Singapore are also provided monthly free iPhone programs and free upgrades with every new iPhone firmware released by Apple so that they will not be stuck with the older firmware version.

These days, the fanatics from is busy with building live support chatrooms, forums, and possibly video conferencing to increase their support and servicing efficiency especially for overseas customers. All these additional stuff are built on top of their monthly newsletters with free iPhone programs and free iPhone updates to their customers.

While it is not known when the iPhone will arrive in Singapore officially, but has already built a small community of proud and quality iPhone owners. We just could not find a bigger iPhone fan than those of

>Cell Phone Facts

>As a cell phone user, you probably feel overwhelmed with all the changes that are coming about with cell phones. Cell phones are ever changing with new gadgets, services, and phones being released on a continual basis. Below we've put together some cell phone facts every user should know. Don't get caught in a cell phone trap, but become educated before you make your next phone purchase.

Cell Phone Batteries

Every cell phone user occasionally experiences the "race against battery life" on their cell phone. You try to use up every ounce of power there is before recharging. Unfortunately, this can cause many problems with your battery later on. Primarily, it could shorten the life of your battery between charges to the point where you're charging more than you're talking!

There are several ways to prolong the life of your cell phone battery. Keep your backlight off unless you know for sure you'll need it. This might be annoying at first, but it will save battery life. When traveling in areas where there is no coverage or there is only roaming coverage, turn off your cell phone completely. The cell phone uses a lot of battery power while trying to locate a network. In addition, try to limit your conversations on your cell phone. The longer you talk, the more battery power you will use. Also, limit your usage of cell phone games or Internet browsing. These use a lot of battery power even though you're not actually talking.

Downloading Woes

When downloading Web features, games, ringtones, wallpaper, and screensavers, be sure there are no recurring fees. Although companies may not state it upfront, some of these features have recurring monthly fees. If you purchase a cell phone for your child, find out if you can block these features. Or, find out if there's a way that you as a parent can order features, but your child cannot.

The Fine Print of Cell Phone Purchases

When buying a cell phone with a one- or two-year contract or pay-per use agreement, be sure to read the fine print. Consider how many minutes you plan to use the cell phone each month. Weigh the prices of both types of agreements before signing on the dotted line. If you plan to use the cell phone a lot, then a long-term contract might be worth it.

Consider the features you want. With long-term plans, you can often get more features on your cell phone for less money or even as a bonus at no charge. Ask if all your features, such as caller ID, will work when roaming. Also with any plan, consider if long distance is included. Find out the usual roaming charges, connection fees (if applicable), and if there are any other hidden fees in the plan.

Ask about Factory Warranties

Some cell phone companies will replace your cell phone if it breaks or is lost or stolen. Consider the warranty of a cell phone before buying. Cell phones are typically carried everywhere you go: in a purse, pants pocket, shirt pocket, on a belt case, and even out in wet weather. With cell phones being so mobile, they can easily get broken or damaged. The warranty will give you peace of mind when carrying and using your cell phone.

Buying Cell Phones Online

When buying cell phones online, be sure the phone is up-to-date and carries all the features you want. You can buy your cell phone online and still visit a local venue to purchase minutes or to sign up for a contract. Just be sure and buy from a company you trust.

There are also electronics shopping malls online where you can find many brand names of cell phones, a PDA, or other electronics at discount prices, such as Sony, Nokia, Motorola, Samsung, Blackberry. You can shop for other products while at the mall, including PS2 machines or games, computer supplies, iPods, and an Xbox.

Use these cell phone tips to find the phone you need for work or play!

>Mobile Phone Technologies

>Mobile phones have become indispensable and now play a big part in everyone's lives. With the current technology that has made people and nations closer, mobile and handheld devices can truly be considered great inventions and innovations. Gone are the days when one has to go home first before he can use the telephone or go to a public phone booth to place an all-important call to a loved one or business contact. With the presence of mobile phones, everyone has now gone wireless. Communication has, indeed, turned very easy for all.

Mobile phone, as it name suggests, provides mobility. It is portable communication device. One can bring it anywhere. It is made possible by satellites that transmit signals for the phone to send and receive. It is very convenient as one can use it anywhere irregardless of time and region.

People everywhere have seen the evolution of communication technology. From a phone that uses wires to one that no longer requires any. From the analog to the wireless. In some places, wireless phones were provided with signals by the network company. In other places, a simulated card in inserted in the phone to grab and receive signals and send as well. These phones use the concept of signal transmission and radio wave theories that enables a two-way communication with real time and clearer conversation. 

From the analog mobile phones that only allowed calling and voice conversation evolved the mobile phones that have text messaging features. It is another emergence in the world of mobile technology. A person may send a text message that will be received by another party. This message is sent through a signal passing to a gateway which transmits it to the receiving party.

In the turn of the 20th century, mobile phones have become more of a trend and companies have started to make them appear more sophisticated. Mobile phones started with big sizes which transformed to smaller ones and then became bigger again. It has developed much like how computers have. Nowadays, mobile phones are not just for communication. Originally, it had the voice call function but since the technology is growing day by day, the mobile technology grows along with it. Mobile phones now have been created with different functions and usage which are beyond plain communication usage. These functions are constantly updated and additional features are created each day.

Mobile phones also serve as mp3 players and/or audio, video file storage units where users may save audio files and listen to the music. Mobile phones now are also equipped with cameras that come in different pixels allowing people to take pictures anywhere and anytime. Almost all mobile phones of these times are designed with games, calculator, organizer, alarm clock, dictionary and many more. These are just now considered the basics. Some updated mobile phones may now take video clips and still photographs of which may be transferred to the computer for different purposes. Many mobile phones are also designed with   touch screen features where a person doesn’t need to touch the keypad anymore. The screen of the phone is designed to recognize commands as the finger tip touches the screen.

Moreover, mobile phones are now used as computers. With the General Packet Radio Service (GPRS), surfing the internet is now made possible. GPRS is used to transmit IP packets which enable users to use the internet wherever they go. People also use their mobile phones in banking transactions where they can send and receive money through phone.

Several high technology features are continuously being researched and applied to mobile phones. Not long ago when 3G system was developed. It enables users of the same networks call each other with real time camera. Through this system, one can actually see the person he is calling while talking to him. Long before people finally get familiar with the just launched 3G system, many companies are now researching on the higher system which is the fourth generation or 4G system. Researchers project the new system as faster with a connection speed reaching 100 Mb per second. This is seen to provide a better quality of call. 

Mobile phones are not only for personal use like it was in the past. With mobile phones, reporters and journalists may now take and film news reports. Security system and surveillance are also possible. 

It is seen in the near future that mobile phones are most likely to replace laptops. With the new mobile phones coming out of the market, viewing and working on documents only found in computers are now possible. It is also seen to replace entertainment devices with all the entertainment features new mobile phones have.

Mobile phones do not only play a big part in technology. Mobile phones also show fashion and style. Thus, to make these phones more appealing and attractive, manufacturers produce these phones in different colors, size, shape, and style. 

Mobile phones are indeed one of the greatest contributions of technology. It has gone far beyond what man can imagine. Now, with the emergence of mobile technology, everyone just can’t live without one.

>Modern Mobile Phones

>Learn how the modern cell phone got to what it is now by comparing it with its past versions. Be able to choose wisely from the current popular mobile phones by knowing the multitude of features these phones have.

Communication has quickly evolved over the years. The telephone reached great heights but there was one thing that was holding it back. This was because of being connected to a phone line at all times, making it impossible to bring around wherever you may go. Thus the invention of the mobile phone, otherwise termed as cellular phone or cell phone for short.

Mobile phones definitely made a splash upon their release to the public. No longer were people unable to leave their home phones in order to get calls from others. They would bring their mobile phones anywhere with a signal coverage to make and receive urgent phone calls or even just have a chat. Having a mobile phone is a luxury. After all, people enjoy chatting. Earlier versions of mobile phones enabled the user to call another mobile phone user anytime and anywhere. It was that convenient.

Soon, newer mobile phones were developed to further enhance communication. These cell phones had Short Messaging Service, or SMS, which allowed cell phone users to compose written texts and send them to others, who in turn can read these messages on their cell phone screen. This revolutionized a whole new communication trend.

The parts of communication involve a sender, a message, and a receiver. Modern phones with text messaging capabilities accurately abide by this principle. The only factor different with traditional communication to text messaging is that traditional conversations integrate feelings with their messages. Whenever a person speaks, his/her voice, tone, and pitch can be methods to express his/her feelings. With text messaging, the message is purely bland, although later on people developed styles of creating emoticons, which are basically a group of letters, numbers, or symbols illustrating faces expressing different emotions.

Mobile phones shortly developed Multimedia Messaging Service or MMS which allows the sending and receiving of pictures, videos, and music files. Soon, a multitude of other features were added as well, including GPRS, WAP, and EDGE, which were basically used to access the internet through the mobile phone.

With the addition of cameras, integrated MP3 players, and wireless connectivity such as infrared and Bluetooth technology, mobile phones were slowly turning into versatile multimedia devices. They rival even the functionality of the digital camera, and MP3 player. No wonder sales of these devices faltered while the sales of cell phones increased dramatically.

Cell phones are evolving faster every time. The current selection of mobile phones mostly incorporates 3G technology and wireless internet access.  Other than the usual text messaging and voice calls, you now have the ability to view the person you are talking to with this 3G technology. Talk about a huge leap in the field of communication!

If you plan on buying a popular cell phone, take time to learn the variety of selections first. There are basically three types of cell phones in the market today. The first is the basic budget handset. It has all the basic functions you can expect from a mobile phone, minus the flashy gadgets and functions. They are basically plain and simple text and call mobile phones. The second is the multimedia phone. It still has the basic text and call feature, along with hardware peripherals such as cameras, wireless connectivity and more powerful speakers for music. Some also have built in radio as an added feature. The third type of cell phone is the smart phone. It is usually aimed for those business people on the go. The features include a full QWERTY keypad, named after the first sequence of letters in the computer keyboard. The smart phone has all the advanced features considering its very expensive cost. These features include wireless internet connection and browsing, email, and various applications that enable the user to view documents that can only be normally viewed using a computer.

With this selection in mind, you may want to reflect on what cell phone category you want to choose. First, consider your budget. Do you have the adequate finances to buy a brand new popular cell phone? Then, you should think about how you will use the cell phone. Do you find yourself actually needing those extra features in your everyday life? Do you actually need wireless internet connection on the go if you are already retired for instance? But don’t think poorly of this functionality. For example, if you are a typical student, you can use your cell phone for convenient web browsing. This would save you a lot of time. Therefore, it is wise to think it over before buying.

Part of what drives you to buy these popular cell phones would probably be due to the appeal of these gadgets to the general public. They are definitely eye candy. These gadgets are currently one of the luxurious items that everyone craves. Mobile phones are now established as status symbols in society. The newer the cell phone, the more popular you become. The more expensive the cell phone, the richer they regard you.

There is no great mobile phone. It is the perspective of the buyer that makes it so. There are so many phones that cater to different people with different statuses. What’s great for one group of people may not be great for another. Choose whatever phone you feel right for you.

Today, there are more people owning cell phones than people having regular phone lines at home. This speaks well to the mobile phone market. It is expected that mobile phones will still be a popular luxury for a long time.

>Bluetooth Definition

>Bluetooth is a specification for the use of low
power radio communications to wireless phones,
computers, and other network wireless devices over
short distances.  The name Bluetooth is actually
borrowed from Harald Bluetooth, a Denmark king
more than 1,000 years ago.

The technology of Bluetooth was primarily designed
to support simple wireless networking of devices
and peripherals, which includes cell phones, PDAs,
and wireless headsets.  The wireless signals that
are transmitted by Bluetooth cover short distances
of up to 30 feet, generally communicating less
than 1 MPps (Mega Byte per second).

The networks of Bluetooth feature dynamic topology
called PAN or a piconet.  The piconets contain a
minumum of two and a maximum of eight peer devices.
The devices will communicate using protocols that
are part of the specification. 

Even though the Bluetooth standard will utilize
the same 2.4 GHz range as 802.11b and 802.11g,
the technology isn't suitable for a Wi-Fi
replacement.  When compared to Wi-Fi, Bluetooth
is much slower, limited in range, and actually
supports less devices.

For short range devices, Bluetooth is rapidly
becoming the best.  The technology is more popular
with cell phones, as Bluetooth headsets are the
way to go these days.  To use Bluetooth, your
cell phone will need to have it enabled, or an
infared device somewhere on the phone.

Upcoming devices are utilizing Bluetooth as well,
such as PS3 and the Nintendo Revolution.  The
wireless controllers will be Bluetooth enabled,
which will give players the cutting edge.

If you own a cell phone or other wireless device,
you should look into Bluetooth.  The technology
is nothing short of spectacular, making it
something that will be around for years and
years to come.  As technology gets bigger and
bigger, you can expect Bluetooth to advance
as well.

>Bluetooth Glossary

>Below, you'll find a list of the most used terms in
Bluetooth technology.  They can serve as a look up,
or to help you learn more about Bluetooth terms in

2 in 1 handset
The situation where a subscriber's handset is acting
as a remote handset to a base unit that provides a
network connection.

Third generation, referring to the next generation
of digital phone technology.

802.11 WLAN
A wireless LAN specification defined by the IEEE.

Access code
Each base band packet will start with an access code,
which can be one of 3 types - CAC, DAC, and IAC.


Asynchronous Connectionless Link.  This is one of the
two types of data links that are defined for Bluetooth.

Authenticated Ciphering Offset.

Active mode
During the active mode, the unit will actively

The above is more of an intro to the terms that are
used with Bluetooth.  Bluetooth currently has hundreds
of devices, making it the best wireless solution in
the world.  With more coming out every day, you can
bet that Bluetooth will be around for many years to

If you are new to Bluetooth, the terms used can be
very helpful.  There are hundreds of glossary terms
that apply to Bluetooth, many of which describe
shortcuts to common terms.  You can learn a lot by
reading over the meanings, especially if you have
never used Bluetooth technology before.

Those of you who have experience with Bluetooth,
can look over the glossary of terms to brush up
on your knowledge or just check out what an unfamiliar
term actually means.  Nothing is complicated with
the meanings, although they make take some getting
used to.

Once you have been around Bluetooth for a while,
you'll find yourself right at home with the terms
and meanings to the technology.  All you need to do
is play around with it, and read books or manuals
whenever you get the chance.  Before you know it,
you'll be a professional

>Bluetooth In Action

>In the United States, Bluetooth gets absolutely no
respect.  It is however, becoming more and more
common in notebooks, PDAs, and especially cell
phones.  Bluetooth will provide wireless users a
way to transmit small amounts of data over short

Now, Bluetooth is facing stiff competition from
new wireless technology.  Referred to as UWB or
Ultra Wideband, it promises data transfer of up
to 480 MB a second - while most current Bluetooth
devices transfer data up to 721 KB a second.

For the time being, Bluetooth devices are surely
cropping up.  Below, we will look at some of
the accessories offered with Bluetooth technology.

Talking to the dashboard
When pairing it with a cell phone, the CCM Blue
Warrior car kit becomes a great speaker phone that
plugs into the power adapter of your vehicle.  The
noise cancelling microphone will reduce background
noise efficiently, with the large buttons making
adjusting the speaker volume a snap.  Although
the Blue Warrior is far from sexy or sleek, it's
very practical.

Tiny tuning box
Part MP3 player and part hands free phone, the
compact and lightweight Sony HBM-30 is an attractive
gadget that lets you accept calls with minimal
interruption of your tunes.  When you get an incoming
call it will automatically pause your music, then
you speak into the built in microphone that you
can wear around your neck or clip to your clothes.

The pen
With Nokia's SU-1B digital pen, you can doodle and
make hand written notes in ink on a special pad
then transmit them from the pad to your Bluetooth
phone.  Being an alternative to typing on a cell
phone keypad, the pen is very handy, although a
pricey tool from MMS fans.

If you want to make slide shows with your camera
photos, the Nokia SU-2 image viewer will let you
disply your pictures on a TV or projector.  Simply
hook this square gray device to your TV's input
with the built in cable, then beam the pictures
to the SU-2 from your Bluetooth enabled phone and
the photo fest will begin.

This device is a snap to set up and use, although
it displays resolutions of up to 640 by 480.  If
you have a newer phone that takes high resolution
photos, you won't be able to use the Nokia SU-2
image viewer. 

Keep in mind, the 640 by 480 pixel photos will
appear blocky on TV screens, no matter what you
do.  If your phone can send batches of photos, you
can create a slide show - although Nokia claims
you can use sequentially beamed shots as well.

>Bluetooth Operation

>The networking standards of Bluetooth will transmit
data via low power radio frequency.  Bluetooth
communicates on a 2.45 GHz frequency.  This very
band of frequency has been set aside by international
agreement for the use of industrial and medical

Many devices that you already known and use take
advantage of this frequency band.  Garage door
openers, baby monitors, and the next generation of
mobile phones all use this frequency within the ISM
band.  Ensuring that Bluetooth and the other
devices don't interfere with each other is a crucial
part of the design process.

One of the ways Bluetooth will avoid interfering
with other electronic devices is by sending out
weak signals of around 1 mw.  In comparison, even
the most powerful of cell phones can transmit a
signal of 3 watts. 

The low power signals will limit the range of a
Bluetooth device to around 32 feet, which cut the
chances of interference between your computer and
other electronic devices.  Even though it has low
power, Bluetooth doesn't require a line of sight
between the communicating devices.  The walls in
your home won't stop the signal, making it great
for rooms throughout the house.

Bluetooth can connect 8 devices at the same time.
With each of those devices on the same radius,
you may think they would interfere with each
other, although it's very unlikely.  Bluetooth
utilizes a technique known as low frequency
hopping, which makes it harder for more than
one device to transmit on the same frequency
at the same time.

With this technique, a device will use 79
individual, randomly chosen frequencies within
a designated range, which change from one another
on a regular basis. 

In the case of Bluetooth, the transmitters will
change frequency 1,600 times or more every
second, meaning that more devices can make full
use of the radio spectrum.  Since every
transmitter of Bluetooth will use spread spectrum
automatically, it's very unlikely that two
transmitters will be on the same frequency at the
exact same time.

When the Bluetooth devices come within close range
of each other, an electronic conversation will
occur to determine whether or not they have
data to share or whether one needs to take total
control.  The user doesn't have any buttons to
press or commands to give - as the conversation
will occur automatically.

Once the conversation has occured, the devices
will form a network.  Bluetooth devices will
create a PAN (Personal Area Network) or piconet
that may fill a room.  Once the piconet has been
established, the devices will randomly hop in

>Bluetooth Profiles

>The profile found in Bluetooth will describe how
the technology is used.  Profiles can be best
described as vertical slices through the protocol
stack.  It will define options in each protocol
that are mandatory for the profile.

The profile will also define the parameter ranges
for each protocol.  The concept of the profile is
used to decrease the risk of interoperability
problems between the different products.  These
profiles won't normally define any additions to
the Bluetooth specification, which is why you can
add new profiles where you need them.  The
Bluetooth underlying technology is the same, only
the specific method that it's used is defined.

Generally speaking, all profiles of Bluetooth are
based on the GAP (Generic Access Profile).  There
are 9 profiles that fall in the GAP category, and
they are below:   
    1.  AVRCP - Audio/Video Remote Control
    2.  ESDP - Extended Service Discovery Profile
    3.  CIP - Common ISDN Access Profile
    4.  PAN - Public Area Network Profile
    5.  HCRP - Hardcopy Cable Replacement
    6.  GAVDP - Generic Audio/Visual Distribution
    7.  A2DP - Advanced Audio Distribution Profile
    8.  VDP - Video Distribution Profile
    9.  HID - Human Interface Device Profile

To put it another way, usage models will describe
Bluetooth device applications and the associated
profiles that are used.  The usage model focuses
mainly on three categories - voice/data access points,
peripheral interconnects, and PAN (Personal Area

The voice and data access points involve connecting
computing devices to communicating devices through
a wireless link. This way, data can be transferred
in a wireless manor, without the need of cables or
other types of connectivity.

PAN  is another very important usage model with
strong appeal to business customers.  Bluetooth
networks are easy to set up in virtually any type
of environment.  An example would be meeting
others at a trade show.

Instead of having contact information beamed via
infrared, business cards can quickly and easily be
transferred via Bluetooth wireless.  The fact is
that many documents can be exchanged this very
same way - making the uses and possibilities
virtually endless.

The Bluetooth profile is very important to the
specification, as it enables you to do so much
more.  You can use peripherals and devices with
the profiles, and virtually anything else that you

As Bluetooth expands and gets bigger and better,
you can count on the profiles to expand and get
even more functions.  If you have experience with
Bluetooth profiles, you should know exactly what
they are and what you can do with them.  If not,
all you need is a Bluetooth device - and a vivid

>Bluetooth Security

>These days, all communication technology faces the
issue of privacy and identity theft, with Bluetooth
being no exception.  Almost everyone knows that email
services and networks require security.  What users
of Bluetooth need to realize is that Bluetooth also
requires security measures as well.

The good news for Bluetooth users is that the
security scares, like most scares, are normally over
dramatized and blown entirely out of proportion.  The
truth being told, these issues are easy to manage,
with various measures already in place to provide
security for Bluetooth technology.

It's true that there has been some Bluetooth phones
that have been hacked into.  Most devices that are
hacked into are normally those that don't have any
type of security at all.

According to Bluetooth specialists, in order to hack
into a Bluetooth device, the hacker must:
    1.  Force two paired devices to break their
    2.  Steal the packets that are used to
resend the pin.
    3.  Decode the pin.

Of course, the hacker must also be within range of
the device, and using very expensive developer type
equipment.  Most specialists recommend that you
have a longer pin, with 8 digits being recommended.

Fundamentals of security
The "pairing process" is one of the most basic levels
of security for Bluetooth devices.  Pairing, is
two or more Bluetooth devices that recognize each
other by the profiles they share - in most cases
they both must enter the same pin.

The core specifications for Bluetooth use an
encryption algorithm, which is completely and entirely
secure.  Once the devices pair with each other,
they too become entirely secure.

Until they have successfully paired, the Bluetooth
devices won't communicate with each other.  Due to
this pairing process and the fact that it is short
range - Bluetooth technology is considered to be

As the news has indicated, experienced hackers
have developed ways to get around this level of
basic security.  There are ways to get around this
threat, as you can install software to prevent
hackers from getting in.

With Bluetooth becoming more and more popular, it's
really no wonder that security is always in
question.  As Bluetooth gets bigger and better,
security will always be something that no one
really takes lightly.

If you've been concerned about Bluetooth security
in the past, rest assured that newer devices will
offer bigger and better security.  Preventing
hackers from getting in is something every owner
is concerned about - and the manufacturer's are
very aware.

>Bluetooth Specifications

>Below, you'll find several specifications for the
well known Bluetooth:

1.  Throughout the United States and even Europe,
the range of frequency is 2,400 - 2,483.5 MHZ, with
79 1-MHz RF (radio frequency) channels.  The
frequency range in Japan is 2,472 to 2,497 MHz with
23 1-MHz RF channels.

2.  A data channel of Bluetooth randomly hops 1,600
times per second between the 79 RF channels.

3.  Each Bluetooth channel is divided into time
slots, with each one being 625 microseconds long.

4.  A Bluetooth piconet has one master and up to
seven slaves.  The master will transmit in even
time slots, while the slaves will transmit in odd
time slots.

5.  The data in a single packet can be up to 2,745
bits in length.

6.  Currently, there are two types of data transfer
between devices - SCO (synchronous connection
oriented) and ACL (asynchronous connectionless).

7.  In a Bluetooth piconet, there can be up to
three SCO links containing 64,000 bits per second
with each one.  To help avoid collision and timing
problems, the links of the SCO will use reserved
slots set up by the master.

8.  A master can support up to three SCO links
with either one, two, or even three slaves.

9.  The slots not reserved for the SCO links can
be used for ACL links.

10.  A single master and slave can have one ACL

11.  ACL is either master to one slave (point to
point) or it broadcasts to all of the slaves.

12.  The ACL slaves will only transmit when it has
been requested by the master.  If the master doesn't
make the request, the ACL slaves won't transmit
anything at all.

>Bluetooth Technology Intro

>The technology of Bluetooth is nothing new, but in
many respects it can still seem like more of a buzz
word rather than an accepted technology.  You may
see the ads for Bluetooth enabled devices, although
you still may be wondering what it is.

The Bluetooth definition is a wireless technology
that is a worldwide specification for a small form
factor, low cost solution that will provide link
between mobile devices and other electronic

Similiar to 802.11 b/g wireless and many cordless
telephone systems, Bluetooth operates on 2.4 GHz
radio signals.  The 2.4 GHz band seems to be a bit
crowded, with interferences between the devices a
bit hard to avoid.  Telephones are now being offered
at the 5.8 GHz frequency band, which will help to
remedy this.

The technical specifications of Bluetooth will
indicate a maximum transfer rate of 723 kbps with
a range of 65 - 328 feet, all depending on the
class of that particular device.  The speed is a
fraction of what is offered by wireless standards,
so it's obvious that Bluetooth doesn't really
pose a threat to replacing your wireless network.

There are numerous products that will take advantage
of Bluetooth capabilities, such as laptops, PDAs,
headphones, and even wireless printer adapters.

A lot of laptops out there will include an onboard
Bluetooth adapter which allows the system to
connect to any Bluetooth device right out of the
box.  For computers that don't have an adaptor
built right in, there are several USB adaptors
available for Bluetooth.

For an awesome technology, Bluetooth is actually
hard to compete with.  For short range wireless,
Bluetooth is easily one of the best.  The standard
for Bluetooth keeps getting better and better,
making it a wireless technology that will be around
for years and years to come.

>Bluetooth Versions

>Version 1.1 and earlier
Since the technology of Bluetooth was introduced in
1998, several specification versions have been
released.  Versions 1.0 and 1.0B had too many issues
and problems for manufacturers to develop devices
for Bluetooth.  The main issue was the lack of
communication among the devices.

The core specification version 1.1 is the first
successful operating version of Bluetooth.  Version
1.1 corrected a majority of the bugs and problems
found in earlier versions.

Version 1.2
Many of the newer Bluetooth devices, such as the
newer cell phones are being sold with the newer
Bluetooth version 1.2.  This version offers backward
compatability with Bluetooth 1.1, faster transmission
speeds, received signal strength, and a host
controller interface (HCI) support for 3 wire UART.

Bluetooth version 2.0
It's true that there may be multiple communication
technologies, although they all share one common
trait - faster is better.  Bluetooth specialists
realized this, and therefore worked on improving
the speeds of version 1.2.  The newest version,
version 2.0 + EDR (Enhanced Data Rate) was
accounced in 2004 and became available in late

Version 2.0 delivers data transfer rates of up
to three times that of the original version of
Bluetooth.  Version 2.0 also provides enhanced
connectivity.  With Bluetooth 2.0 + EDR, you'll
be able to run more devices at the same time -
with more efficiency.

Computers and even computer related devices are
expected to be some of the first devices to
encorporate Bluetooth 2.0 + EDR, followed of
course by audio and imaging devices. 

Version 2.0 is backward compatible with previous
versions, three times faster, and offers an
enhanced data rate of 2.1 MB a second.  It also
offers broadcast and multicast support, along
with a further enhanced bit error rate
performance, making it the best Bluetooth has
ever seen.

>Bluetooth Wireless Networking

>Bluetooth technology offers three different types
of defined ranges, based on output ranges.  Class
1 devices are the most powerful, as they can have
up to 100 mW of power, with a regular antenna
giving them a range of around 130 - 330 feet.

The class 2 devices are lower power, offering up
to 2.5 mW of power. A regular antenna will give
them a range of around 50 - 100 feet.  Class 3
devices use even less power, up to 1 mW of power
to be exact.  With a regular antenna, they will
have a range of around 16 - 33 feet.

Even though you may not realize it, Bluetooth
wireless technology has never been intended for
anything other than short distance types of
communication. With Bluetooth wireless, the short
range is actually a benefit.

For one, the short range will reduce the change of
interference between your devices and those that
belong to others who are nearby.  Overall, this
is a basic type of security, designed to protect
you and your devices.

Secondly, the lower power used for short range
means a longer battery life.  Most Bluetooth
devices will get their power from a battery,
meaning that anything you can do to lengthen the
battery life is very important.

The wireless networking offered by Bluetooth is
actually among the best, even though it uses
short range communication.  Bluetooth is used
with wireless controllers, the internet, and
even wireless headsets.

For the best in short range technology, Bluetooth
is extremely hard to beat.  If you've never tried
Bluetooth before, now is the time.  It's the best
with wireless networking, especially for those
who enjoy hands free talking on their cell phone.

>Choosing A Bluetooth Headset

>Creating a good wireless headset for Bluetooth is
actually difficult to do.  The regular wired headsets
are easy to design - with ranging styles. 

Bluetooth headsets can never be as small or as light
as wired headsets, simply because it needs to include
the battery and extra functions. This extra size
will impact how the headset mounts on or around
your ears.

There seems to be two main styles of headsets for
Bluetooth.  Some are held into place with a loop
around the ear.  These styles are normally more
comfortable, although they may be less secure.  The
others are held in place by being jammed into
your ear - and usually prove to be less comfortable.

Factors to consider

The cost is an obvious issue, something that you
really need to think about.

    1.  Check to see if the device is easy to
quickly and conveniently put on your ear then take
it off again.
    2.  Are the control buttons on the headset
easy to use?
    3.  The headset should be comfortable to
wear for long phone calls.
    4.  Can you use it with a pair of glasses?
    5.  Check to see if you can wear it with
either ear.
    6.  When you aren't wearing it, you'll
need to se how you would carry it with you.
    7.  The weight is important as well, as you
don't want something that has the risk of falling

Ease of use.
    1.  The commands and controls should be
easy to remember.
    2.  The volume level should be easy to
    3.  The unit should turn on quickly.
    4.  The manual should be very well written
and easy for you to understand.
    5.  There should be a support number for
you to call if you should experience any types of

    1.  You'll need to know about the battery,
the talk time, type, and how to tell when it is
going dead or fully charged.
    2.  How many devices can the unit be paired
    3.  Compatability is also important, as
well as the warranty period.
    4.  Check the sound quality for both
sending and receiving audio.
    5.  What type of range does the headset offer

Other important capabilities include voice tags,
last number redial, tranfer calls, 3 way calling,
link to other phones, call reject, and mute.  You'll
also want to note if it looks attractive, and if
it's too big or too small.

>Connecting Many With Bluetooth

>Constantly evolving, the technology of Bluetooth
started off as a basic wireless connection standard
but has since then been adapted and proven with many
different uses and functions.

A good example is Bluetooth for cell phones.  It
enables mobile users to connect to their hands free
headset without using wires.  Bluetooth technology
will also allow mobile phone users to connect
with their hands free kit as well.

Another handy use of Bluetooth is file sharing.  It
allows the sharing of files between two cell phones,
between a cell phone and computer, which makes the
sharing of files a snap.  If you have a cell phone
and computer, you can easily transfer data between
the two.

Say for example you wanted to put an MP3 on your
phone from your computer you could do it easily
with Bluetooth.  All you would need is a Bluetooth
adapter for your computer.  It doesn't stop with the
swapping of files either,as you can use your computer
and phone to synchronise phone books, send SMS messages,
and much more.

Although Bluetooth may be dandy for cell phones,
it also comes in handy for the home office as well.
Utilizing Bluetooth is a great way to set up a
home office - two computers, a printer, and even a
scanner.  They all can be connected using Bluetooth
technology with effective ranges of up to 10 meters.

The technology and devices of Bluetooth will be
around for years and years to come.  As years go
by, Bluetooth will provide even better wireless
solutions for different applications.  Even though
Bluetooth has a short range, it has that short
range for a reason.  Bluetooth is easily the best
in wireless technology - which it continues to
prove time and time again.

>The Bluetooth Solution

>The technology of Bluetooth will take small area
networking to the next level by removing the need
for user intervention and help keep transmission
power very low to preserve battery power.  Each
transmission signal to and from your cellular
phone will use just 1 mw of power, giving you
plenty of space on your battery to talk.

Bluetooth is a networking standard that will
work on two levels:
    1.  It will provide agreement at the
physical level, as Bluetooth is a radio frequency
    2.  It will provide agreement at the level
of protocol, where products will have to agree
on when bits are sent, how many are sent, and how
the parties in conversation can be sure the message
recieved is the same one that was sent.

The major draws to Bluetooth is the fact that
it's wireless, inexpensive, and automatic. There
are other ways to get around wires, including
infrared.  Infrared uses light waves of a lower
frequency than the human eye can, and is normally
used in television remote controls.

The technology of Bluetooth is intended to get
around the problems that normally come with
infrared systems.  The 1.0 older standard of
Bluetooth has a max transfer speed of 1 MB a
second, while the 2.0 Bluetooth standard can
manage up to 3.0 MB a second.  To make things
better, 2.0 is compatible with 1.0 devices.

As a solution to wireless, Bluetooth will
eliminate the need for messy cords, keeping
everything nice and neat.  It's perfect for those
who like to talk on cell phones, as you no
longer need to hold the phone next to your
ear - which is great for those who travel a

>The Future Of Bluetooth

>Because it meets the basic needs of connectivity in
close range, Bluetooth has a very bright future
ahead of it.  Bluetooth is actually the result of
initiatives from nine leading communications and
computer industry giants, including 3-COM, Sony,
Lucent, IBM, Nokia, Microsoft, etc.

Since the forming of the original group, more than
1,800 manufacturers around the world have joined
the initiative.  According to reports, the Bluetooth
technology is expected to be built into more than
100 million devices, with over 670 million enabled
Bluetooth devices.

Resulting from the amazing success of WAP (Wireless
Application Protocol), the adoption of smart phones
and hand held devices, Bluetooth can easily have
an amazing impact on your day to day life.  Bluetooth
is one of the key technologies that can help to
make the mobile information society happen, by
blurring the possibilities between home, the office,
and the outside world.

The seamless integration and connectivity that
Bluetooth promises will make it possible to explore
a wide range of interactive and highly transparent
personalized services which were actually quite
difficult to dream of simply because of the
complexity involved with making such devices
communicate with each other.

Many Bluetooth pilot products have already been
rolled into the market and backed by big vendors,
which is a healthy sign for the overall acceptance
of the technology.  The support for Bluetooth isn't
limited to companies that develop only Bluetooth
enabled products.

The applications for Bluetooth can have great
impacts on other industries as well.  The adoption
of Bluetooth technology is expected to spread
throughout the industry of computers. 

Unlike infrared technology, Bluetooth is used by
many different wireless devices.  Bluetooth offers
exceptional quality for short range wireless, even
going through walls and obstructions.  While
infrared is the biggest competitor at this time,
Bluetooth far surpasses it, proving to millions that
it is the wireless communication technology of the
present day and age.

In the beginning, Bluetooth started with version 1.0,
then gradually moved from there.  The current
version is 2.0+EDR, with another version currently
in development.  The technology behind the Bluetooth
specification always getting better and better,
which is why it's so popular.

In the future, you can expect the technology
behind Bluetooth to get better.  Bluetooth has
proven to be the wireless standard of the future,
offering you wireless connectability for hundreds
of different devices.  For cell phones or other forms
of wireless connections, Bluetooth is the one
technology that you don't want to find yourself

>Using Bluetooth

>The amazing technology of Bluetooth presents a great
way of exchanging data between two wireless devices.
Unlike telephones, there are no wires or messy
leads to worry about.  You can enjoy wireless
communications with short distances of up to thirty

Bluetooth also offers interoperability, meaning that
you can use your portable Bluetooth device to connect
with existing Bluetooth points.  This way, you won't
have to carry a data lead or CDs of drivers around
with you everywhere you go.  You can enjoy the best
of wireless without having to worry about installing
your software.

With today's Bluetooth, you can use your PDA and cell
phone to surf the net or check emails as you travel.
If you are in the business field, this can be very
beneficial, especially if you like to check your
email throughout the day.  Bluetooth will enable you
to check your email no matter where you are - which
is great news for those who like to travel.

Bluetooth will also enable to you to transfer files
as well, such as MP3 and photo to and from your mobile
device.  Bluetooth dominates the world of short range
wireless, enabling you to do more than you may
have thought possible.

One of the best things to Bluetooth and something
everyone loves is the wireless headset.  Bluetooth
offers wire free headsets for your cell phone or
computer, which is great for those who like to walk
around or talk on the phone in the car, without
having to worry about your hands getting in the way.

To make things even better, you can use a Bluetooth
GPS device for satellite navigation on your PDA,
laptop, or mobile.  If you travel - this can be
really great to have.

>Bluetooth Basics

>The technology of Bluetooth wireless is a short
range communications method intended to replace
the cables that connect portable or fixed devices
while maintaining the highest levels of security.

The key features offered by Bluetooth include
low power and low cost.  The specification in
Bluetooth defines a uniform structure for a wide
range of devices to communicate and connect with
one another.

The technology behind Bluetooth has achieved
global satisfaction such as enabled devices, almost
everywhere in the world.  Bluetooth devices will
connect and communicate without wires through
short range and networks known as piconets.

Each device will simultaneously communicate with
up to seven other devices within a single piconet,
meaning that each device can also belong to
several piconets simultaneously.  The piconets
are dynamically established as Bluetooth enabled
devices enter and leave the proximity of radio.

A fundamental to Bluetooth strength is the
ability to handle both data and voice transmissions
simultaneously.  This will enable users to enjoy
varieties of innovative solutions such as hands
free talking, printing and fax capabilities,
and other applications.

Unlike other standards of wireless, the Bluetooth
specification gives product developers both a
link layer and application layer definitions,
which will help support data and voice applications.

The Bluetooth technology operates in the industrial
and scientific band at 2.4 to 2.485 GHz, using a
spread spectrum, frequency hopping signal. 

The adaptive frequency hopping of Bluetooth
technology was designed to reduce interference
between wireless technologies that share the 2.4
GHz spectrum.  Adaptive frequency hopping (AFH)
works well within the spectrum to take full
advantage of the frequency available.

AFH hopping allows for more efficient transmission
within the spectrum, which provides users with
greater performance even if they are using other
technologies along with Bluetooth. 

>Bluetooth Applications

>With Bluetooth being very popular with wireless, it's
no wonder there are many applications available for
the technology.  Below, you'll find the applications
for Bluetooth.

1.  Wireless networking between laptops and desktop
computers, or desktops that are in a confined space
and little bandwidth is needed.

2.  Peripherals such as mice, keyboards, and printers.

3.  Cell phones with Bluetooth technology have been
sold in large numbers, as they are able to connect to
computers, PDAs (Personal Data Assistant), and various
other devices.  The standard also includes the
support for more powerful and longer range devices.

4.  The transfer of files, images and MP3, between
mobile phones.

5.  Certain MP3 players and digital cameras to
transfer files to and from computers.

6.  Bluetooth technology headsets for smart phones
and cell phones.

7.  Data logging equipment that transmits data to
a computer via Bluetooth technology.

8.  Sony Playstation 3 and Nintendo Revolution will
both use Bluetooth technology for their wireless

For Bluetooth, there are literally hundreds of
different applications and devices available for you
to use or purchase.  As you may already know,
Bluetooth is the most popular wireless technology
in the world.  It's very reliable, very dependable,
and very hard to crack into.

There are many other applications for Bluetooth in
development now, many of which plan to take the
wireless age to the next level.  Video game systems
are using Bluetooth technology as well, for their
wireless controllers.  This is great news for gaming
fans, as Bluetooth offers the best in wireless
data transmission.

If your curious about applications for Bluetooth
that are still in development, you can search on
the internet.  You can find all sorts of information,
especially when it comes to Bluetooth.  As the
future arrives, you can expect Bluetooth to bring
bigger and better things.

>Bluetooth And Apple

>The new Apple powerbook G4 are among the first
computers to offer Bluetooth technology 2.0+EDR.
The 2.0+EDR technology, which still backwards
compatible with 1.0, is up to three times faster
than previous versions, offering maximum data rate
transfers of up to 3 MBps.  Being the first company
to certify a system with 2.0+EDR, Apple continues
to make great use of the Bluetooth technology.

Full support
In addition to the powerbook G4 portables, there
are other Bluetooth enabled computers available
from Apple, including the iBook, iMac G5, eMac,
and the Power Mac G5. 

Making life easier
When you turn the Bluetooth feature on, your Mac
can easily perform a file transfer or even a
synchronization.  From the Bluetooth selection
menu, you can choose to either send a file or
browse devices, quickly and easily.  Or, you can
click the sync button in iSync to update your
cell phone or Palm OS handheld. 

The Mac and GSM/GPRS mobile phone with Bluetooth
work to make each other more useful.  By using
iSync, you can keep your phone updated without
having to type any info, as you can keep the
information in the more manageable address book
on your Mac instead. 

You can also use your Bluetooth enabled Mac to
print documents and digital images to select a
printer that also supports the technology of
Bluetooth.  Or, you can also use a headset to
talk to your friends during an iChat session.

Your Mac also has the ability to use Bluetooth
technology to communicate with your Palm OS
handheld.  This way, you can perform a HotSync
operation without using any cables.  You can also
send your business card or calendar events directly
to someone else's handheld usingthe technology of

The implementation of Bluetooth by Apple is the
latest in a series of moves that have caused
great shift in the computer industry.  Apple
established USB as the standard interface with
the launching of the first Mac back in 1998.

Since then, Apple established the 802.11 wireless
standard of networking with the launch of the
iBook and AirPort in 1999.  During 2003, Apple
launched AirPort Extreme, which was based on
the new 802.11g high speed technology of wireless.

Now, Bluetooth helps to further strengthen the
dominant position of the Mac in wireless
communications, helping to preserve Apple's
reputation for being the first to market with
innovative technology that integrates right into
the operating system.

>Bluetooth Technical Operations

>Bluetooth is a high speed, low powered wireless link
technology that's designed to connect phones or other
portable equipment together with little to no work
required by the user.  Unlike infrared, Bluetooth
doesn't require line of site positioning to work.

Current prototype circuits are contained on a board
that is 0.9 cm square, with a much smaller circuit
board being developed. 

When one Bluetooth device comes in contact with
another, they will automatically exchange addresses
and details of capability.  Then, they can establish
a 1 MB link with security that they will use as
required.  The protocols involved with handle both
data and voice, with a very flexible topography.

The technology achieves its goal by embedding tiny,
non expensive short range tranceivers into the
devices available today.  The radio operates on the
2.45 GHz frequency band, and supports up to 721
KBps, along with three voice channels. 

Each devices offers a unique 48 bit address from
the IEEE 802 standard, with the connections being
point to point or multipoint. The max range is
10 meters, although it can be extended to 100
meters by increasing the power.  The devices are
also protected from radio interference by changing
their frequencies, also known as frequency hopping.

What's important, is the fact that Bluetooth
devices won't drain battery life.  The specification
targets power consumption of the device, limiting
the drain on the battery.  The radio chip will
consume only 0.3mA in stand by mode, which is less
than 5% of the power that standard phones use.

Bluetooth will also guarantee security at the bit
level.  The authentification is controlled by the
user via a 128 bit key.  The radio signals can
be coded with anything up to 128 bit.  With the
frequency hopping, Bluetooth is already very
hard to listen into.

The baseband protocol is a combination of both
circuit and packet switches.  Slots can be reserved
for synchronous packets as well.  Each packet
will be transmitted in a different hop frequency.
Normally, a packet covers a single slot although
it can be extended to cover up to five slots.

Bluetooth can also support data channels of up to
three simultaneous voice channels.  Therefore,
it's possible to transfer the data while you talk
at the same time.  Each individual voice channel
will support 64 KB.

From a technical standpoint, Bluetooth is very
different indeed.  It's the best wireless method
in the world, surpassing even infrared.  For
communication on the go, Bluetooth is indeed
very hard to compete with.

>Three Cell Phone Companies

>The first cell phone I remembered ever seen was the one that Sack Morris in Save by the Bell used to have. It was big and it looked more like a portable phone than a cell phone, and it was not very common for people to have unless you were a business man. However now a days everybody has a cell phone, and the smaller they are, the better. With the invention of new technology cell phones have improved and now you can even take pictures with your cell phone, and even better, make videos.  Also you can navigate the internet, write an email, and even take it to another country and still be able to use it. Furthermore they have the possibility to send messages instead of calling people which makes it more affordable and easier to use. Today cell phones are so popular that some people rather have cell phones than have regular phones. Also information and pictures taken in your cell phone can be transfer into a computer which is great to connect people since these pictures and information can be send or simply be save for a longer time in a computer.

What's more impressive than cell phones themselves is the amount of companies that sell cell phone services, which is good because it creates competition, which creates lower prices. Here in Venezuela there are three major companies: Digitel, Movilnet, and Movistar, which is good because one have the opportunity to compare the different rates and sales that these companies have to offer. My family have Movistar because we have a service ¨Habla Pegado¨ that allows you to talk to any other Movistar as long as you want, which is excellent and cheaper in a family of a large number of people like ours: two parents, and seven children.

>Lost Your Cell Phone?

>As the use of cell phones becomes increasingly popular, so does the use of cell phone lanyards to keep them from being misplaced.  The cell phone lanyard is also a great way to keep a cell phone readily available without having to physically carry it.  The lanyards are typically made of cord, rope or wire.  They can be connected to a backpack, belt loop or purse.  To keep a cell phone easily accessible it may be most convenient to wear a cell phone lanyard around the neck, keeping the hands free.

When worn around the neck, the typical cell phone lanyard, measures 36 inches long but can be custom designed to any length.  To secure the cell phone to the lanyard, simply pull the lanyard through the lanyard hole that can be found on most cell phones.  Other cell phone lanyards have a nylon cord attached to the end that can be pulled through the lanyard hole.

Although born of necessity, the cell phone lanyard does not have to be boring.  There are many styles, colors and materials to choose from.  Custom printing can display a favorite slogan, symbol or saying. 

Many talented artists will design you a unique beaded cell phone lanyard to coordinate with a favorite outfit, pair of shoes, as well as your automobile.  Choice of beading includes gemstones, pewter beads, Swarovski crystals and even diamonds.

>Samsung cellular phone

Samsung cellular phone, a basic phone

Cellular phones are now getting to be a necessity in this modern society.  This is not how they foresee the cellular phone future some years back.  Luckily, manufacturers are quick to recognize the booming cellular phone industry. Thus, they are able to answer the growing demands for this functional toy. Additionally, the introduction of various functional features for cellular phones by huge cellular phone companies makes cellular phones more a need to perform specialized tasks.  Because of this, the use of a cellular phone is getting to be a requirement for business executives in going about their various tasks as they go about their business.  However, not everybody needs these special functions, some only needs cellular phones for basic use like sending and receiving calls.  If you do not require these high technology functions, buying a cellular phone for basic use may only be what is necessary.  Some cellular phones are for basic use including Samsung cellular phones.  It is more reasonable to buy basic cellular phone models if you do not need to play with your cellular phone and Samsung cellular phone may be what is the best for your.

Samsung cellular phones are generally of good design.  They have wide and clear display, which is beneficial especially for sending and receiving text messages.  Samsung cellular phones have good battery life compared to other cellular phone units.  As already mentioned, these cellular phones are good cellular phones for basic use.  Samsung cellular phones have beautiful designs; you may be pleased to choose one among the various models that will fit your need.  You will not despair buying a cellular phone from Samsung if you only require the basic features; beauty of the product is thus a bonus.  However, if you are looking for functional cellular phones more than the basic sending and receiving calls and text messages, Samsung cellular phone is not the one for you.  People who want to play and require so many functions and features will not enjoy a the cellular phone from Samsung.

Some basic complaints encountered with Samsung cellular phone, which happens only to very few users, are choppy calls and scratchy and distorted volume generation.  This only happens to very few users, and to ensure you will not experience this in a Samsung cellular phone, you may ask the recommendation of the friendly Samsung staff. 

Some who endeavor to find functionality in a Samsung cellular phone give it a nickname “very good yet slightly bad phone.  It is very good because the designs are superb and the battery life is good.  Slightly bad because some high-tech features fail in Samsung cellular phone, precisely it is a cellular phone for basic use.

Do not expect Samsung cellular phone for other features rather than the basic ones, no picture transfer, no internet communication and some phone do not support blue tooth usage.  Not a techy’s choice indeed.  Some people who buy this phone feel that with the superb design, it should include additional feature and functionalities.  The company is on its way to developing the phone you require, researches and product development are now on the drawing board.

For some who could not wait, buying Samsung cellular phone is still a neat choice because the designs are upbeat and beautiful.  The added bonus is that the battery life is longer than other cellular phones.  Enjoy the basic functions and beautiful designs with Samsung cellular phones.

Samsung Cell Phones - U Series

Because of the increasing demand for cellular phones

everywhere in the world, manufacturers are faced with

the challenge of designing new and advanced handsets.

There is a saleable trend when it comes to cell phones

or mobile phones. In fact, even Samsung cell phones

are constantly upgrading their cell phone lines and

today, they are offering the U series.

The U series of Samsung cell phones are among the

latest in the mobile phone industry and is competing

with Nokia’s N series, Sony Ericson’s Walkman series,

and Motorola’s RAZR series. Each new release features

progressive runs and so the manufacturers attain

phenomenal success. No matter how expensive the new

cell phone series are, customers are still patronizing

it especially those who want to keep abreast with the

trends. South Korea’s giant cell phone manufacturer,

Samsung, has indeed proven its worth by introducing

the all-new U series.

Statistics say that there millions or even billions of

poor people out there but it doesn’t really matter

because even the poor ones still find a way to

purchase their own handsets. However, for the ever

conscious customers, they now have a new choice. For

those of you who prefer the slim stylish features of

cell phones, get the Samsung U series such as U100,

U300, U600, and U700. If you want a refreshing look,

purchase your U series cell phone now. This is a great

addition if you love to collect different cell phone


The series began with the introduction of the U100 in

the cell phone industry. Its super slim feature has

caught the interests of millions of mobile phone

users. Aside from the cellular phone’s elegant body,

it is also equipped with the latest advanced features.

It therefore is a cell phone with substance and style.

Because of the success of the U100, manufacturers of

Samsung cell phones decided to come up with better U

series phones.

After the U100, Samsung released the U300 and it even

generated more sales than the U100. The manufacturers

simply improvised the U100 and called it U300. They

didn’t expect to get impressive results but customers

really liked the new phone. After the U300, two other

sophisticated cell phones were released and just like

the other two models, sales went higher.

Samsung manufacturers realized the importance of

improvisation and so customers welcomed their new

cellular phones with open arms. Even if the U series

commanded a high price, it did not discourage

customers to buy the handsets. In order to be

competent in the cell phone industry, manufacturers

must always have fresh and new ideas to create better

cell phone models. Change is the only permanent thing

in this world and so it’s no wonder why cell phone

models are upgraded sequentially.

People of today are enjoying the fruits of advanced

technology. Cell phones are becoming more

sophisticated nowadays and even you can’t determine

when you’re phone’s going to be outdated. So what are

you waiting for? Why not try Samsungs new phone line?

If you find the U700 quite expensive, you can always

get the predecessors - U100, U300, and U600.

When shopping for Samsung cell phones, make sure that

you have prepared your budget so that you can

instantly pay for the handset. You can even get the

extras so that you can use your phone with ease.

>Sprint Cell Phones - A Good Choice

>It is a very difficult task to choose only one

cellular phone provider since there are many out

there. People are already familiar with Nokia,

Samsung, LG, and many others but do you know Sprint?

Sprint cell phones are also quite popular and Sprint

is among the leading cellular phone providers in the

mobile phone industry. So why should you choose


If you purchase Sprint cell phones, you can choose

among their wide range of plans. You can get the

monthly plans wherein you will have to pay a standard

monthly bill. The monthly plans will work best for

businessmen or the very busy individuals who often use

their phones. On the other hand, for those individuals

who hardly makes a call unless when necessary, you can

choose the prepaid plan.

The monthly plans offered by Sprint cell phones are

among the best. There are inexpensive plans that let
