I think that it would, but I'm fairly sure that if you (1) plug up your iPod to your computer with iTunes open, (2) hold down the power on/off button on top and the center "menu" button until the screen goes black, then (3) let off of the top button, but continue to hold the menu button until the computer says something about iTunes having found a iPod in recovery mode, then you have fully erased the Touch, and when you restore it, it will be reformated, and no one will ever know it was jailbroken. At least that's what I'm counting on if mine ever breaks!;)
