iPhone 4 follows iPad in pre-order shipping delays

Despite troubles with sales sites, Apple has reportedly sold more than 600,000 iPhone 4 handsets in the opening day of pre-orders, a new record for single day sales.

Apple started taking pre-orders for their new smartphone on Tuesday (June 15th) with the 16GB handset costing £499 and the larger 32GB model going for £599. The staggering opening day popularity, however, crashed the Apple Store website shortly after the new handset went live.

With numbers looking to easily surpass the pre-order and sales figures of previous iPhone models, concerns are now once again turning to Apple’s ability to meet demand.

The UK store, which is only offering pre-orders on the black handsets with white models to come at a later date, has already pushed the pre-order shipping date back from the June 24th launch to July 2nd.

Apologising for the halt to sales following the unexpectedly large volume of online interest that ran supplies dry, an Apple spokesperson said: “We apologise to everyone who encountered difficulties, and hope that they will try again ... once the iPhone 4 is in stock.”

Despite pre-orders kicking off days ago, just one of the six UK network providers confirmed to stock the Apple iPhone 4 has unveiled its prices and tariff charges. Orange, who will offer the iPhone 4 on pay monthly and business contracts or as a standalone PAYG handset will start their charges at £480 for the 16GB iPhone 4 and £570 for the 32GB.
