Hey, Desperartly wanting an iPhone, now its time to get one, I have a job so i can afford one now. I don't want contract, as I'll be moving to the USA in February, so want a phone that works here in the UK with my 02 sim the now, and then buy a sim when I move there. Are these factory unlocked iPhones for real? Anyone purchased one? Experience? Will future updates work? Will inserting an UK sim lock it to the uk network? I know these are probably stupid questions, but would appreciate any and all advice. Thanks you.
