I have a 1.1.4 iPod Touch (16GB) with the apps boughten from the iTunes Store, I want to jailbreak using ziPhone but I have a question. Do I need to restore? I have so much music on there from my friends and what not that I can't get ahold of again. On top of that like I said I bought the apps and don't know if I can re-download or whatever. Do I need to restore my iPod?
