The Apple iPhone can easily be referred to as the one phone that has changed the entire mobile phone industry and the way we look at mobile phones. Gone are the bar styled phones with a traditional keyboard. Those are now replaced by full touch screens that have largely drawn their inspiration from the original iPhone. The iPhone has seen various versions over the years, and the latest one, the iPhone 4 promises to be the best so far.

The new iPhone 4 features a 3.5 inch touch screen display. Apple claim that the retina display technology employed in this screen is the most advanced yet and it produces such a high resolution that the pixels are not visible for a naked eye. The 960 x 640 resolution is one of the highest for a mobile phone screen. The phone apart from this fantastic screen also features a great camera as well.

The 5 megapixel camera used in the phone is just one of the two cameras in this phone. This along with the Facetime application means that you can do a video chat with your family and friends all for free. The 5 megapixel camera is at the rear and it is used for high quality photography. It can also do 720p HD video recording. The camera comes with LED flash that provides great lightning for better low light photography. The phone has connectivity options like 3G and Wi-Fi that lets you share the photos and videos taken on the social networking sites such as Facebook and so on.

The phone also comes with a powerful battery that offers nearly 7 hours of talk time in the 3G mode. The iPhone 4 retails from £499 for the 16 GB version to £599 for the 32 GB version.
