Since the iPhone 4 was announced yesterday all the UK operators have been scrambling around to announce the mobiles availability on its network.

So far we’ve learnt that Apple’s device will be available on O2, Orange and Vodafone. This is totally expected as they all currently offer the iPhone 3GS.

O2 have announced that they will be providing its current iPhone customers with an easy upgrade to the new version . You can pre-register your interest in the iPhone 4 on O2 by clicking here.

Orange have merely announced they will be stocking the device and have offered no more details.

The launch date for the iPhone is the 24th June, which isn’t far away at all and it shouldn’t be long till prices and tariffs appear online.
