Hi all, I have a 3Gs that is currently running on 3.1.3 and is NOT unlocked or JB. I would like to upgrade it to OS4.0 and then JB and unlock. Which on is the best and easiest version to unlock? I've been reading the forums for the past few days but there doesnt seem to be a clear answer in which direction should I go. I was thinking about doing uprgade to 4.0.1 and then just using jailbreakme.com. I'd rather do untethered and not go to the ipad BB (6.15.00) Any advice will be greatly appreciated in the matter!
