But i wanna see what all i can get out of it. 1) I know it's gonna void warranty. Obviously. But is it true that all traces of said jailbreak can be removed by restoring? Also- can i keep going back and forth? jailbreak- restore- jailbreak- restore? 2) Battery life... Does it drain as much as 2.0? 3) What things would i get out of it that 2.0 doesnt already have? 4) Is it idiot proof? i don't want to destroy my ipod in the process. 5) Does this crash like 2.0 does frequently?
