The new Apple iPhone 4 has hit the UK with thousands of gadget fans eagerly anticipating its arrival.
Apple said it has already taken over 600,000 pre-orders for the new iPhone
Apple's latest offering is slimmer and more powerful than its predecessor and features the new OS 4 operating system as standard - making multi-tasking third party apps possible for the first time.
The smartphone offers a higher-resolution display, larger battery, video calling and the ability to record and view high-definition video.
Apple has also installed an oil-resistant glass screen to stop grubby fingers smearing the display.
The company's UK flagship store in Regent Street, London, opened its doors early at 7am to allow fans who had camped overnight to be the first to get their hands on the phone.
The design team at Apple has truly surpassed itself with the iPhone 4 - a super slim version of the 3GS with a whole lot more oomph under the bonnet.

The iPhone 4 had been unveiled earlier this month by CEO Steve Jobs who said it represented "the biggest leap since the original iPhone".
He added: "FaceTime video calling sets a new standard for mobile communication, and our new Retina display is the highest resolution display ever in a phone, with text looking like it does on a fine printed page.
"We have been dreaming about both of these breakthroughs for decades."
Mobile phone expert Ernest Doku, from review site Omio.com, reckons the handset will live up to the hype.
He said: "The design team at Apple has truly surpassed itself with the iPhone 4 - a super slim version of the 3GS with a whole lot more oomph under the bonnet.
"On visual design alone, it's time to trade in the 3GS."
ut others fear it will squeeze smaller firms out of the market.
Luke Peters of T3 magazine said: "One company in particular fearing the arrival of the iPhone 4 will be Flip, creators of pocket-sized HD camcorders.
"With the latest iPhone touting a HD-capable, 720p video recorder of its own, Flip will be worried about its portable HD camcorders becoming less attractive to consumers looking to replace their tech arsenal with a single, all-encompassing device.
"This 'iPhone effect' of a single convergence device replacing the need for several, separate pieces of kit has already become a concern for companies since the arrival of the original Apple smartphone in 2007."
The new handset replaces the iPhone 3GS which launched a year ago and sold over a million units in its first weekend.
However, Apple's most recent hit has been the iPad tablet computer. Over three million iPads have sold since its US launch less than three months ago.
Apple says it has already taken over 600,000 pre-orders for the new iPhone - the most it has ever taken in a single day.
But the new iPhone is facing competition as the next generation of Android-based phones are unveiled.
Droid X goes on sale in the UK on July 15, with Motorola attempting to win sales from Apple.
More than 160,000 handsets that use the Android operating system developed by Google are sold everyday.
