Does anyone know if the 2.1 updates erases all of the apps, music, and movies after the update? How about any apps from jailbreaking (2.0-2.02 still had it when I pwned my iPhone again, at least I think)? iTunes 8 messed up my applications by deleting all of them, and I'd prefer to keep them in the same order I have on my iPhone instead of getting a completely different order when I resync between my iPhone and iTunes. BTW, QuickPwn couldn't come quick enough for Windows.
