    I'm in Korea and brought an iphone from the US. I got it at game stop, and it was an ATT phone. I have watched some videos and I think, I jailbroke it, but I'm not sure if it is unlocked. In "The apple guy video" I got to the point where he put in the new sim,but when I did the same thing mine did not auto recognize it. It said invalid sim. I can't make or receive calls which makes me think it is not unlocked. I would appreciate any help you can give. Other information I'm using SK as my provider in Korea.

    If cydia is installed it is jailbroken.

    If it gives invalid sim its not unlocked.

    What Baseband versionbyou have?
    You can fins that in Settings/General/Info
    At the bottom it says modemversion.

    I think what he means to say is it cannot be unlocked !
    And he is correct, the only unlock option is a carrier IMEI unlock.
