right now i have an unactivated 3gs, and i only have a tmobile sim card.. i can only access the emergency call screen right now and nothing else, it apparently has ios 4.1 on it. any ideas what i can do here to at least get into the iphone? i dont want to activate with att (no sim card). (the iphone is on the connect to itunes screen and itunes says sim card not supported, to get an official carrier card to activate)
