Ok i restored my firmware from apple 3.0 by opening itunes shift restore and damn i dun have an at&t sim card lying around to activate and my power button is broken lol i was curious if theres an way to activate my iphone 3g at 3.0 firmware? since jailbreaking/acitvating requires dfu mode or could i just shift + click restore and restore an custom firmware without going recovery mode or dfu mode?
