Is there a way to mess up my ipod touch while jailbreaking?

Nope, it’s normal for the iPod to restart while Jailbreaking. Plus, if anything terrible does happen you can always hook it up to iTunes and restore it.

@ breefield: i already unplugged and plugged in my iPod but strange codes appear on the screen, and iTunes is not able to find my Ipod. btw. this was after i stopped the process twice while it was jailbreaking

Dude I hope your iPod isn’t messed up cuz you stopped it while you were jailbreaking it….I have no clue what you did to it.

Hum…I haven’t jailbroken my iPod anytime recently. I’d suggest restoring it and waiting a month for the appstore to come out.

@breefield: is there a way to restore or reset my ipod without connecting it to the computer?

Nope
