I live in China and brought over my AT&T iPhone 4S, but the thing is locked and is useless over here. I could buy a $30-50 Gevey SIM but I've had bad experiences with that in the past. I currently use a Chinese iPhone 4, but the camera is lacking. I know there was some law about unlocks in the US, has that trickled down yet? Am I correct in assuming that unlocks are now impossible through jailbreaking on 7.1+? There are IMEI seller things around, does that really work? It just seems too expensive to buy for a $100 phone.
