Hi guys, I just got my first iTouch the other day, sooo excited over it. I jailed it with RC5 and I wanna go to RC6 the moment it becomes stable. Will I have to restore it first on iTunes and then jailbreak its ass all over again? :'( That'd be really inconvenient. Or can I just "stack" it on top of RC5 no problems asked? Also, is there a way to make a "snapshot" of all my iTouch data so in the case of serious error I can just revert right back to it? Thanks guys!
