Hi guys, I've been having some issues with my jailbroken iPhone, so I thought it might be a good idea to restore it to a clean state and re-enter the data. Situation: 1. jailbroken iphone 3GS using jailbreakme.com method on 4.0.1 2. Want to upgrade to 4.2 and not jailbreak anymore 3. I've already purchased the games I wanna keep (PvZ, angry birds etc) 4. Girlfriend wants to preserve the game save files since she's progressed quite far. Someone suggested that I could just install the 4.2 update over the current jailbreak situation, would that un-jailbreak the phone? I was actually thinking of following the guide here to restore the original settings: http://forums.macrumors.com/showthread.php?t=603129 but I don't see how that can preserve the game save files. If it's possible, I'd like to retain my text messages too. Any help would greatly be welcome. thanks in advance!
