I have tried to get a straight answer on this, but nobody seems to know and the guy at the apple store didnt have any clue either. The wife and I are moving to the UK in february, and her sprint contract is about to run out, so we are really wanting to get iphones. Im not really worried about contracts, since i will be moving on military orders, and are not required to pay all the disconect fees when we leave. My main question is, if we buy iphone 4's now, will we be able to use them in the UK if i jailbreak and unlock them? If anyone can give me info, i would very much appreciate it. thanks!
