I have a couple of questions about jailbreaking on a version 3.0 iPod touch with the latest edition of Redsn0w. 1) I already have a 2.2.1 jailbroken 2G. If I jailbreak to 3.0, will all my themes, jailbreaking apps, etc. still be there, or will I have to redownload all of them? If the new jailbreak will erase all my previous jailbreak data, is there any way I can back up my jailbroken files (themes, apps, etc.) so that they can be used on my 3.0 Jailbroken iPod? 2) Can you use the 3.0 jailbreak on the 2.2.1 device? Do you have to upgrade to 3.0 before using it? 3) Do you have to upgrade to iTunes 8.2 to jailbreak?
