Apple have sold over 600,000 iPhone 4 phones, a record number of pre-orders to receive in a single day. The new smartphone looks set to outstrip sales of previous Apple iPhone models, as well as the strong sales figures of the iPad tablet computer.

Apple’s site was inundated with sales orders, causing the site to exceed capacity and supplies of the device to run out. Apple’s site has remained slow, with the company advising consumers to ‘try again’ and attempt to buy the device once it is back in stock.

Apple said: ‘we apologise to everyone who encountered difficulties, and hope that they will try again… once the iPhone 4 is in stock’. Sales are expected to exceed that of the iPhone 3GS, with an increase in new users purchasing smartphones.

Apple recently saw a serious public relations embarassment, as a group of hackers exploited a flaw in AT&T’s network to access the data of 114,000 iPad users, including the White House Chief of Staff. AT&T have been heavily criticised by iPhone users for dropping calls, and recently withdrew an unlimited data package.

Users attempting to buy iPhone 4 using AT&T’s pre-order system have suggested that the company was confusing information between customer accounts, which could allegedly lead to iPhones being shipped to incorrect addresses.

‘iPhone 4 is the biggest leap since the original iPhone’, said Steve Jobs, Apple’s CEO. He noted the new iPhone’s video calling and high resolution display as key features, saying ‘We have been dreaming about both of these breakthroughs for decades’.

iPhone 4 will be available in the US, UK, France, Germany and Japan on June 24th, starting in the US at $199 for qualified buyers with a two year contract.
