The Good Side Of The Apple iPhone 4 Unlocked Phone
Coming with a processor of 1 GHz and 16 GB of flash memory, the iPhone 4 is one portable and EXCELLENT office and entertainment gizmo that both average users and tech geeks would love! I've owned this unlocked Apple iPhone 4 for about 3 months now and I never had any problem.

Display – it's amazingly sharp and nice. The applications load lightning fast! Matter of fact, I already have 130 apps to get almost every duty you can think of...and to make the deal even sweeter, these apps don't affect the unlocked phone's performance.

I have been in the computer manufacturing and design industry for about 2 decades now and I can confidently...without any doubt, say that this is one of the MOST amazing pieces of technology I have ever laid my hands on. Even the battery life is amazingly good – it can last 3 times longer and better than the previous model. And take note, I'm NOT exaggerating when I say that I have almost no need or use for the laptop.

The Apple iPhone 4 can send faxes, edit Excel and Word Documents, play games with it as well as videos, and even print! What MORE can you ask for?!

With flash for the 5 Megapixel Camera as well as a High Definition video camera, real time video conferencing over wireless network, Bluetooth (which is compatible with everything you throw at it unlike the earlier 3G model), Garmin GPS – there is no doubt that the unlocked Apple iPhone 4 reigns supreme in the smart phone world!

The One And Only Con Of This Unlocked Phone – Which Is NOT REALLY A Bad Thing
I have read those issues about the antenna of the iPhone 4. Well, get this – while an issue, this is easily fixed by slapping a hard case or shell on the phone. This INSTANTLY eliminates the issue. Now, as for me, I have never experienced this problem. Matter of fact, checking now, I'm getting 4 Mbps downloads, which is faster than it was 3 months ago!

Simply put, I'm now a happier iPhone 4 user than I was a couple of months back.

The first great feature of the iPhone 3G is the intuitive, attractive interface. Needless to say, Apple knows how to make simple, beautiful products. The iPhone 3G has an extremely responsive touch screen, combined with an amazingly elegant interface which allows for point and click multi-touch. It is, without a doubt, a device with one of the best touch screens in the industry currently.

The second great feature of the iPhone 3G is the App Store. The App Store service currently offers over 225,000 paid and free third-party applications. Although it's not exactly an exclusive service for the iPhone 3G, the App Store makes the iPhone 3G a device with an infinite amount of capabilities. With an app for just about any type of situation, the App Store and iPhone 3G combine for an extremely versatile product. Not many phones in the industry can produce this type of usability.

The third great feature of the iPhone 3G can be said to be the various other goodies which come with the phone. It has an extremely well designed body. It runs on a 3G network, which is fast and reliable for the amount of data that the average user would transfer. It contains the functions of an iPod also, allowing users to listen to music as effectively on their phones as they would on their iPod. It comes with a great 2MP camera that allows for instant upload onto social networks such as Facebook. And finally, it comes with great Apple firmware, which includes the MobileMe functions along with other business friendly features that make the iPhone 3G the perfect phone for any type of business.

While not necessarily a great step forward from the original iPhone, the iPhone 3G builds upon an amazing product. With faster speeds and more great features, Apple expands on its iPhone enterprise, making it one of the best phones on the market.

First of all, we must understand the name change. Many people wonder why the iPhone 3G only evolved to have an extra S. Well, the S stands for speed. Being one of the primary complaints from customers, speed was one of the main issues of the original iPhone. After it was upgraded to the 3G network, people still believed that Apple had not stayed true to the promise of speed. The new iPhone 3GS is fast. In fact, it downloads and surfs almost twice as fast as its predecessor. The speed is noticeable as the lack of delay time in opening iPhone apps.

Another important feature of the new iPhone is the battery life. As many iPod and iPhone owners know, Apple products tend to lack the battery life that the company promises. However, the new iPhone promises an amazing 10 hour battery life on video, 9 hours on web browsing, and 300 hours of standby.

Finally, the iPhone 3GS features some amazing new firmware. The new firmware 3.0 is yet another step up from the Apple software. Including more advances to the MobileMe features and many other features which were requested by Apple users, the firmware finally makes true some of Apple's promises. It even supports video, which has been demanded since the iPhone first came out.

Arriving at $199, the iPhone 3GS is an improvement over the original iPhone. However, it would be false to say it is a breakthrough. Although the new iPhone has amazing speed and some great features, it is in fact, not quite that much different from the iPhone 3G. Many customers who don't have too much need for speed may even decide to get the original iPhone 3G instead, which is now priced at only $99. However, for people who enjoy surfing the web frequently on their iPhone, it may be time for an upgrade.
