Hey everyone, I have to help someone unlock a 3GS on iOS 4.1 Baseband 05.14.04 Which tool would I need to unlock this iPhone with? Obviously you need to be JB first before you can unlock the device. If by chance he isn't already JB...what tool would I JB 4.1 with on a 3GS?? I'll be doing this on my laptop so I don't really want to update it to 4.3.1 and make him lose all his info and stuff. Please advise....thanks in advance!
