Simple question really. Bought an iPhone second hand, want to restore it as fresh as possible. Hovered over the 'restore' button in iTunes when the above question popped into my head. The phone currently has 3.13 on it, and I would ideally like to keep it! Thanks,
Why would you want to stay on 3.0? 3.1.3 is more stable, bug free and all appstore apps will work with it. You can still JB and unlock a 2G iphone on 3.1.3 you know.
