ok so I know this is possible through redsn0w on a mac running 10.5. I have bought the 3.0 firmware cause I dont want a pirated version to mess something up. Now my question is, i'm already jailbroken on 2.2.1, and i have a bunch of apps and tweaks and such from cydia. If i jailbreak to 3.0 untethered will all that data be lost? Or can it simply be replaced with a restore to a backup file? I really dont want to go back and re-download EVERYTHING. Cause i already will have to wait like 3 hours for my 35 hours of music to be copied over... If your answer includes going to another website please link, so others reading this with a similar question can get through this process allot easier. Thanks in advance guys. EDIT: AAACK! WROOONG FORUM... this is supposed to be in 3.0 discussion. wow that flew right over my head... sorry.. if i knew how to move this i would but i dont..
