Been wondering about this for awhile. QuickPwn can jailbreak an OS without restoring, but I've been wondering if its possible to jailbreak and upgrade the OS without restoring. I hate having to download all my music (10gigs) from my ipod, then restoring, updating, jailbreaking and then put all my music back. Is this an actual possibility or are the OS's so dependent on a restore that this method would be impossible? Any thoughts?
