If you have been following the tech scene, then you should have already had a glimpse of what the new iPhone will look like. For those of you who havn’t already seen it, Apple today officially showcased their long awaited iPhone 4 at the WWDC in San Francisco.

Apple showed off their new piece of tech with a ton of new and exciting features. Firstly with an upgraded design, where the internals are sandwiched between two hardened plates of aluminosilicate glass with a stainless steel trim which stretches around the outer edges which acts as the phone’s radio antennae. At a mere 9.3mm, the iPhone 4 is 24 percent thinner than its predecessor; the iPhone 3GS.  Referred to by Apple as the “retina display”, the LCD screen boasts a 960×640 high resolution display with 326 pixels per inch and a contrast ratio of 800:1.

Along with the new aesthetics, the battery has also been upgraded with a proposed 7 hours of talk time, 6 hours of 3G browsing or 10 hours on Wi-Fi, 10 hours of video, 40 hours of music and a potential of 300 hours on standby. Formerly known as the iPhone OS 4, the new OS has been renamed to a more suited iOS 4 since it will also power the iPad and iPod touch.

The camera has also been blessed with an updated 5-megapixel sensor with LED flash and 5x digital zoom and support for 720p video recording at 30 fps. In addition to the back camera, a front-facing camera was also added which will allow users to take advantage of Apple’s FaceTime to make video calls.

The iPhone 4 will be available in two colours; black and white, and will be released on June 24^th in the US. The phone will be more widely available to the rest of the world by September. In the US the 16 GB version will cost $199 with contract while the 32 GB model will be $299.

With all the new features, Apple continues to impress and hold a firm position in the mobile phone industry enticing new developers to their device.
