Hey guys, I recently bought an iPhone 4 from this guy online, and it was an AT&T iPhone that has been jailbroken and unlocked with ultrasn0w on 4.0.1. This iPhone is currently activated and completely functional. However, this iPhone is synced to his iTunes library, and I will have to restore it in order for it to work with mine. Here is the problem. I'm living in New Zealand, and this AT&T iPhone is only working right now because of the ultrasn0w unlock. If I restored it to 4.0.1, to my knowledge, the iPhone will become deactivated. If so, how can I activate it again? The iPhone 4 currently has no jailbreak method that works like PwnageTool (which can hacktivate it). I can only jailbreak it with JailbreakMe if it's been activated. The iPhone 4 can't function here in NZ unless it is jailbroken and unlocked. Can someone tell me what I should do in this situation? Is there any way to activate the iPhone if I restore it? I currently have a Vodafone NZ MicroSIM.
