Apple’s Steve Jobs to unveil the new iPhone 4G

Apple’s chief executive Steve Jobs is set to unveil the latest fourth-generation iPhone at the company’s Worldwide Developer Conference in San Francisco later today.

The iPhone 4G (also known as the iPhone HD) is expected to boast a five-megapixel camera with flash; a smaller, lighter, and slimmer handset; a glass back with improved reception; micro-sim cards similar to the iPad; a faster A4 processor (like the iPad); a larger, sharper 960 x 640 pixel screen; improved battery life and iChat software.

Users are likely to have a choice between a 32GB and 64GB handset, from Apple’s existing retailers Orange, Vodafone and O2.

The Apple 4.0 operating system has a number of new features including multitasking (for example, so music apps can play while you make a VOIP call), folders to organise apps, iBooks, Apple’s mobile ad system iAD, improved mail options and gaming options.

Details of the new iPhone were leaked in April, after a prototype of the handset was sold to the gadget blog Gizmodo.

Apple has now passed Microsoft to become to most valuable technology company, having sold more than 51 million iPhones since its launch in June 2007 and 2 million iPads worldwide since they went on sale in the US on 3 April.
