My case came with this screen protector made of thick plastic that was formed to the dimensions of the ipod touch display (e.g. no cutting, it was made specifically for it.) It bonded using static cling and was basically perfect for the job. But it took a few heavy scratches (none of which made it to the screen!) and I need a replacement. What brand sells these kind of thick screen protectors, pre-cut for the ipod touch 1g?
