Ok. I got another iPhone from a friend, who was using it legitimately with ATT and upgraded fully to 2.1; I want to unlock it and use it on another carrier. I know that the 2.1 update changes the baseband, and can interfere with using it on another carrier. How do I downgrade the baseband? Will pwnage take care of it, or do I need to downgrade, then create the custom firmware and upgrage again?
Any help is greatly appreciated. Or anywhere with some info.
