Do you want to jailbreak iPod Touch 2.2.1? It’s good to jailbreak because you can modify your iPod and make it look the way you want it to look. Right now you can’t jailbreak iPod Touch 2.2.1 because the jailbreak is being developed by the iPhone Dev Team. Just wait for the QuickPWN download to be released. Don’t update iPod Touch 2.2.1 yet.
