Hi I just bought a used iphone from this guy: The phone can turn on and use the applications like youtube and all (except for the phone calling ability) WITHOUT a sim card. Does that mean the phone has been activated? He jailed breaked the phone with installer 3.0b or something like that. However he doesn't seem to have the phone unlocked for non-at&t user. The problem is I don't know if he had this phone 1.1.1 out of the box or 1.0.2 upgraded to 1.1.1 (I'm still waiting for his emails, thank god i checked the phone before buying it) so I can proceed in which method to use as virginizing the phone then unlock it. I haven't buy a Sim card yet but will do so in a few hours. Where do I go from here? My main objective is to get this phone unlocked for T-mobile. Thank you. If I violated any rules, sorry.
