A lot of myths exist regarding as to whether the cell phone cameras are any good or not. The fact that people require to admit that these cameras are also digital cameras and they exhibit the same facilities irrespective of the fact that their sizes are much smaller and their functionalities are curtailed due to this particular reason. Hence some introspection needs to be done regarding the digital cameras and cell phones in their joint venture together in the technological world!
Looking back into the initial stages of development the availability of low-cost, low-power CMOS imaging modules helped to charge up the popular craze camera enabled cell phones in today's world that primitively began in Japan. That proved to be contagious for the rest of the world. From young students to even busy business people avidly annals photos of colleagues and whatever else passes in front of their phones. The popularity has touched sky high and the reason being the good quality that people seek at grass root level endeavors of photography. Americans have the urge to seek betterment in these areas also. They go about to seek cool new digital camera phones that all have VGA resolution 640 x 480 pixels. This is considered a safe bet that this phone is the most expensive model.
Much of a kind of ignorance exists apart from all this regarding the cell phones cameras and it crops from the fact that no benchmarks exist for objectively comparing picture quality in image sensors, camera modules, or end products. The helpless consumers thus have to rely upon advertisements to tell them much. Yet this is not a correct way to knowing a technical device. Considering the technological portion it can be said here that in the cell phone cameras some of the VGA handsets offer fairly good image quality. When you consider that the resolution comes from an imaging module that measures only 6 mm square, its actually pretty amazing quality. That square includes an imaging chip, a digital signal processor (DSP) that supports the VGA format, and a double lens that's packaged in a light-tight module. Finding room for this module is easy. Plus, power consumption is low because the imaging chip is CMOS.
Considering the further improvements in the cell phone camera technology it can be stated here that some cell phones have incorporated conventional CCD imaging units that are still used in most digital cameras today. These devices require high voltage and a bigger a battery. As a result, CMOS has taken over in VGA-resolution applications. It provides increasingly good image quality. All this discussion shows the various achievements in the technology. However it must be stated here that the cell phone cameras are really good but they are nothing compared to the actual digital cameras. The sole reason being that they are much larger and contain far more features. It must be admitted here that such comparison is irrelevant because they are definitely two separate areas of work in spite of the fact that they are both digital cameras. Yet they are diverse in 100% of all their aspects. Hence the comparison is irrelevant.
Considering all the important points discussed in the above lines regarding the various areas of the cell phone digital cameras it comes out to be something that is worth appreciation. Leaving aside all comparisons they cell phone cameras are digital cameras that are certainly good in their areas of applications and mass acceptance and popularity would some day make them as advanced as their pioneer professional digital cameras.

The Cell Phone Batteries
By Roy D'Silva
The cell phone may well be the most important invention in recent times. This little communications device has played a major part in making communications simpler and making people believe that if wireless communication over a certain distance is possible, so is data transfer across continents.
While the cell phone was a mere device to take and receive calls a few years ago, today the cell phone is on the verge of becoming a complete portable entertainment device, with just one of its features being making calls.
However, the cell phone is not a standalone device. It has many complicated and important parts within itself, without which, the basic need of a cell phone is defeated. One such important component of the cell phone is the cell phone battery. Earlier, cell phones used to contain NiCad (Nickel Cadmium) batteries. These batteries had low power and were also heavy.
It is suspect whether these batteries could sustain power enough for a cell phone to double up as a digital player, let alone be digital camera and MP3 player. Surprisingly, the most battery using feature of a cell phone is connecting to the Internet. Back in the days of WAP, the NiCad batteries would lose their power after about half an hour of internet browsing using the cellphone.
Success Stories and Failure
The cellular battery is an integral part of the cellphone. Though it may seem completely dispensable, there have been times when people have kicked themselves for not having a spare battery. In fact, may cellular models of many handset companies could never take off because their batteries didn't have the capacity to power all their features.
The battery life and the range are two reasons why the number one cellular handset company in the world is the number one cellular handset company in the world today.
Innovating Success
Batteries today are made of NiMH (Nickel Metal Hydride), which plays an important role in making the cell phone light and breezy to use. The NiMH batteries also are less prone to have the 'memory effect' as compared to NiCad batteries. The NiMH batteries are also known to give a better performance as compared to their counterparts, NiCad batteries.
The recent entrants in the market are Lithium-ion batteries and Lithium Polymer batteries.Batteries made of either material weigh less than both NiCad and NiMH batteries and give a superior performance. In fact, the Lithium-ion and Lithium Polymer batteries can power the latest cellular phones in the market today for a full week.
Precautions
One should be careful while using batteries. Batteries normally have a 500 recycles lifetime. After this, the batteries may decrease in standby as well as talk time power. Simply put, any battery will work well for not more than two years. One should also be careful enough not to overcharge the batteries.
Overcharging the batteries may result in the battery to overhead and finally damage the mobile phone battery. A cellular battery typically attains full charge in three to four hours.
Also, avoid exposing your cellphone to extreme heat or cold. Also, do not let the cellular battery be dormant for a long time. Another good idea is to keep the battery terminals in the cellphone clean. If the battery is to be kept dormant for an extended period, it is suggested to take the battery out of the handset and store in a cool, dry place until use.
Deciding Factor
The battery life of a cell phone has always been a deciding factor in the buying decisions. One should decide as to which cellphone is to be bought, and which features would be used at present or in future. It is extremely necessary that a feature-rich cellphone should have a strong and robust cellular battery. One other option is to always keep a spare battery, for those days of long chats.

How can I access M-Commerce by SelfBank Mobile Financial Blogger Todd Schuyler. I hope you enjoy this blog article review. M-commerce (mobile commerce) is the buying and selling of goods and services through wireless handheld devices such as cellular telephone and personal digital assistants (PDAs). Known as next-generation e-commerce, m-commerce enables users to access the Internet without needing to find a place to plug in. The emerging technology behind m-commerce, which is based on the Wireless Application Protocol (WAP), has made far greater strides in Europe, where mobile devices equipped with Web-ready micro-browsers are much more common than in the United States. But now, with Free SelfBank Mobile Banking and Payments, M-commerce is going to a whole new level, not requiring special software or hardware and can work on any phone or carrier and POS system.
In order to fully exploit the m-commerce market potential, handset manufacturers such as Nokia, Ericsson, Motorola, and Qualcomm are working with carriers such as AT&T Wireless and Sprint to develop WAP-enabled smart phones, the industry's answer to the Swiss Army Knife, and ways to reach them. Using Bluetooth technology, smart phones offer fax, e-mail, and phone capabilities all in one, paving the way for m-commerce to be accepted by an increasingly mobile workforce.
As content delivery over wireless devices becomes faster, more secure, and scalable, there is wide speculation that m-commerce will surpass wireline e-commerce as the method of choice for digital commerce transactions. Were talking about alot of people!
Financial services, which includes mobile cell phone banking (when customers use their handheld devices to access their accounts and pay their bills) as well as brokerage services, in which stock quotes can be displayed and trading conducted from the same handheld device.
Telecommunications, in which service changes, bill payment and account reviews can all be conducted from the same handheld device Service/retail, as consumers are given the ability to place and pay for orders on the spot.
Information services, which include the delivery of financial news, sports figures and traffic updates to a single mobile phone device IBM and other companies are experimenting with speech recognition software as a way to ensure greater security for m-commerce transactions.

About the Author:
A cellphone number lookup service provides an easy way to find information on a cellphone number that called your work, home, or mobile phone. You might like to check on your partner in case they are cheating, or you may have missed an important business call. Cellphone number lookups can get you the information you need, without leaving your computer.

The bad news is that a growing number of the phone numbers we're seeing aren't from landlines. Free services won't be able to help you if you're researching a cell phone or unlisted number.
In those cases, you'll need to turn to a paid service. That's not such a bad thing, usually because you'll end up with more accurate, up-to-date information and, you'll learn more about the individual who owns the number than you probably imagined possible, like family members, relatives, and background information.
The registration process is simple and you only need to do it once. With most services, your membership entitles you to an unlimited number of searches, so in the future you only need to log in to find what you need.
As soon as you have registered, you will be able to carry out a cellphone number look up. All you need to do is enter the area code and all the digits of the phone number your looking for information on. Then hit search and the system will match the number you put in to its extensive database.

Find Out How To Trace A Cell Phone Number
By Paul Turner Marketing.com
About the Author:
The need to trace a cell phone number usually comes from some degree of pain caused by receiving anonymous phone calls or text messages from people you don't know or don't want contacting you. This is a growing problem all over the world in these challenging times.
You can trace or find landline numbers easily because these phone numbers are already in the public domain - ever heard of the phone book? But cell phone numbers don't have the same books. Phone networks such as Verizon and sprint don't make it easy for us. There are now some good, websites that make it easy to find cell phone numbers by compiling their on cell phone directories.
A cell phone number directory is the answer. These will allow you to do what is known as a reverse cell phone number look up. This sounds rather grand but basically you enter a cell phone number and the directory uses this as its search field and follows the line of information back to the owner of the phone.
First of all try and find the number for free by simply typing it into Google. Perhaps the owner of the number has entered it somewhere where you may find it. It is a long shot but worth a try.
How a reverse cell phone number works is simple. Some sites let you enter the cell phone, or landline number into the directory before you part with money, so you know if there is information before you before you hve to part with the modest fee. Some sites expect you to pay before you know if they have any information and you should avoid these. You will then be given the information concerning that number, which will include a name and sometimes an address.
People are using cell phones to make more prank calls,sales calls and threatening intimidating calls and text messages because cell phone numbers aren't that easy to trace back. They think they are protected but this now not the case with the growing number of reverse cell phone directory websites.
