right now i have a first generation ipod touch, its in 2.1, its jailbroken, and its been like this for a while, i want to upgrade to 2.2 though. if i upgrade (in itunes) to 2.2, will i lose all my stuff, and lose the jailbreak? and have to re-jailbreak my ipod and redownload everything i had? im not going to try updating right now, just incase i do have to redo everything when there may be an easier way. any help on how i could update firmwares would be nice. thanks.
