My son has an iPhone that when he did a restore it would not activate. we tried a few sims and nothing doing. Is there a way of finding out what carier it is locked to so that maybe we can get an official unlock?
Well, I don't know what to tell you...where was the "tourist" from? Model numbers are meaningless in trying to determine the origin of an iPhone. At one time they were an indicator, but that's no longer true.
