No. Jailbreaking an iPod Touch voids your warranty. If you send them the device anyway Apple will be able to detect that you have jailbroken your device and refuse to repair it. Wrong, jailbreaking an ipod touch became legal a long time ago... and with my research i can prove that if apple refuses to fix it, you can sue them and you will most likely win. sooo yeah that doesnt ruin ur warrenty

A jailbroken iPod Touch is certainly legal. However, the act of getting every app in the App Store for free (the ones that require payment) is illegal.
Currently, the iPod Touch 3rd generation cannot be jailbroken because it has a built-in firewall of sorts, a measure taken by Apple to prevent the iPod Touch from being jailbroken. There is a jailbreak software currently being beta-tested, but is not ready for public use.
