I got Ghost Armor done on mine, not sure where all they're located, I know they're here in the Phoenix area, a couple at Best Buy's.
Ghost Armor | cases, screen-protectors, shields, skins, covers, armor
Mine was a custom fit, as the kit wasn't available and I just wanted the screen done. I'm 100% happy with it. I've had it on my iTouch as well.
Edit: Does help that it was professionally installed.
