The iPhone 4 was finally unveiled last night at the World Wide Developers Conference, following months of leaks, rumours and counter-rumours.
Dubbed the world’s thinnest smartphone, the handset is 24 per cent thinner than the 3G S at 9.3mm thick. The latest iteration of Apple’s handset also addresses a number of concerns aired by owners of the last edition with improved battery life and imaging capabilities.
The 3.2 megapixel camera of the current-generation 3G S edition has been replaced by a five megapixel snapper with a backslide illuminated sensor, five-times digital zoom, LED flash and a touchscreen focus interface. As was widely predicted, the camera is capable of 720p HD video recording at 30 frames per second.
Also onboard is a secondary front-facing camera for video calling, which is teamed with Apple’s new built-in FaceTime software. However, this will initially work only with Wi-Fi networks, with no indication when it will be enabled for use with 3G.
Additionally, the iPhone 4 is home to a 3.5-inch super high-density Retina Display which renders pixels invisible to the human eye and which was touted by Apple Chief Executive Office Steve Jobs as “quite a bit better than OLED”. The screen offers resolution of 960x640 and packs in 614,400 pixels. By way of comparison, this is quadruple the number of the 3G S.
In a break with earlier versions, the smartphone will be available in a choice of black and white. However, storage capacity options are unchanged at 16GB and 32GB.
The inclusion of a larger lithium ion battery means that users can expect up to seven hours of talk time on 3G networks and up to 14 hours when 2G is in use. This has also boosted media playback, with owners able to listen to a maximum of 40 hours of music or view videos for up to ten hours.
To facilitate multi-tasking the iPhone 4 will come with the latest, faster version fo Apple’s software IOS4 and packs a 1GHz processor, bringing it in line with rival smartphone challengers such as the HTC Legend and the Google Nexus One.
