And yeah you could jailbreak it, but it does void your warranty because it violated the EULA you agreed to when you turned it on the first time.
However, I had a 1st generation jailbreak'd iPod touch which got a broken headphone jack. All I had to do was restore it to original settings and the Apple Genius who gave me another one, didn't have a clue :P
But that was 6 months ago, they could (and probably do) have a way to detect if your iPod is/was jailbroken.
