Is it safe to jailbreak your touch? If you value your warranty then no, it is not. If you don't then it probably is. The iPod Touch is no iPhone. There is no messing with modem firmware or anything like that here. It's just tweaking the OS. If all goes wrong then in theory a restore should always get you back. However, in theory there is no difference between theory and practice but in practice there most certainly is!

Basically, it's probably safe but you are still taking a risk.
