Apple opens details on new iPhone 4

Heralded as the biggest leap since the original iPhone with over a hundred new features, the iPhone 4 was unveiled today to huge cheers at this year’s Worldwide Developer Conference in San Francisco.

Powered by Apple’s A4 processor, the device is 24 per cent thinner than the iPhone 3GS – making it the thinnest smart phone on the market.

It features front and rear facing cameras with an LED flash, a gyroscope as well as the accelerometer, and a micro-SIM slot.

Design-wise, it features squared lines and steel edging that serves as an antenna, compatible with Bluetooth, wi-fi, GPS, UMTS and GSM.

The demonstration heavily emphasised the new Retinal Display, so named for having 326 pixels per inch, whereas the human eye can process up to 300 pixels per inch.

It features a 960 x 640 display on a 3.5-inch screen, with a 800:1 contrast ratio that is four times better that the iPhone 3GS, and IPS technology for better colour and a wide viewing angle.
