UK iPhone owners subscribed to O2 will indeed be allowed to unlock for other carriers, according to the CEO of O2's parent company, Telefonica Europe. "Once the iPhone becomes available on other UK networks," says Matthew Key, "we will allow O2 customers to unlock their iPhones, although of course they will still need to honour any outstanding contract period they have. At the end of their contract period, they are entirely free to move to another operator -- though naturally we hope they won't want to!"
