The iPhone 4G was last night announced by Apple CEO Steve Jobs at the company's World Wide Developers Conference (WWDC).
Jobs said customers would be able to pre-order the long-awaited iPhone 4G from Apple's online store by 16 June, and the handset would be on sale at Apple retail stores from 24 June. T-Mobile, Orange and Vodafone are expected to offer the device on contract in the UK.
Carphone Warehouse has also launched an online iPhone 4 pre-order page, enabling web users to register for their iPhone 4 well in advance. Phones4u has also announced that it will be stocking the iPhone 4.
Carphone Warehouse CEO Andrew Harrison said the company was "expecting a stampede of customers to hit our stores as soon as the handset is available.”
US prices for the new device were announced as $199 for 16GB version and $299 for the 32GB model. The iPhone 3GS is now available for $99.
The newly launched iPhone 4 runs Apple's iPhone 4.0 OS, or iOS 4.0 as it is now called, and comes with multi-tasking capabilities, dual cameras for video chats and HD video recording.
