Hey, I've got an iPhone 3GS 4.1 BB 05.13.04 new bootrom, and I want to update it to 6.0.1 and jailbreak it. For that I used sn0wbreeze, to create a new custom firmware. I chose the simple mode so it wouldn't change my BB since I want to unlock it, once it is in 6.0.1 .. The problem here is, I can't get through error 1600,1601,1602. When I try to restore the iPhone it verifies with apple store and gets stuck there, then the error shows up. I tried editing my hosts, rebooting, w/e, nothing worked. Any idea where I'm doing wrong?
