hi. i really want to update my ipod touch (1st. gen.) to the 2.2 software. i've heard that a LOT of people have had trouble with it like...ipod not turning on, computer won't recognize ipod, ect... i really want to update my ipod, but i don't want it to break or anything, so has anyone SUCCESFULLY upgraded their ipod? if so how did you do it? please answer if you can, thanks.
