Well, sort of. If you jailbreak correctly (I didn't), your music and videos will be temporarily wiped, along with apps. However, I think app save files are stored in the iPod firmware, so you should keep saved games if you use one of your recent backups to jailbreak.
This is speculation, and I can't vouch for it's accuracy, but it seems right. Maybe someone else here knows more?
If you are planning on jailbreaking the iPod Touch 2G then I'm pretty sure you have to use the PwnageTool which does in fact wipe your iPod clean.
hey guys, i just jailbroke using quick freedom, and it restored the ipod with the custom firmware, now itunes detected a new ipod and is asking me if i want to start a new one or restore from back up. i want all my old stuff and i backed it up right before i jailbroke, but im just wondering if doing this messes up the jailbreak. thanks =]
I put restore from backup and my iPod was EXACTLY the way it was(settings everything) before I jailbroke. Along with cydia and installer of course
thanks!
