Hi I need help from someone please. My cousin came here from Sri Lanka, he has a factory unlocked iPhone 4 that he bought from the apple store in Canada, he got a friend that lives there to ship it to him, it worked fine for him in Sri Lanka this whole time, it's be almost a year, He came here a week ago and he gave me is iPhone so I can update it and stuff. Now I just updated it to ios 5.1.1 and it's asking me for a compatible sim and stuff. He went to T-Mobile when he first came here and he didn't know but he bought a gevey sim anyway and has been using the gevey sim with t mobile, but now when I try to activate it I tried three different sims, an AT&T, Red Pocket and T-Mobile but nothing is working, I'm getting really frustrated it's been three hours so please can someone help me. Thank you.
