I jailbroke my 3GS using Jailbreakme.com, and it's still running 4.0.1 (8A306). Now I want to update to 4.1.3. I've downloaded redsn0w 0.9.6rc11 and iOS 4.3.1, but I'm not sure about something: Will I have to go through the activation/verification process and unlock again? Or will the unlock I already did stick? I don't remember if I still had my AT&T SIM when I did the original jailbreak and unlock. I'm now in Haiti with no access to the AT&T network -- though I do have an old but still active Cingular prepaid card. Perhaps relevant info: When i open Cydia, it says SHSH 4.0 4.0.1 4.0.2 4.1 4.2.1+ 4.3 Baseband is 05.13.04 Thanks!
