I don't have an iPod touch 4th generation yet, but it will becoming within the next week or two. I only have one screen protector, and I'd hate to put my last one on my new iPod only to find that it has some sort of issue and that the screen protector is now useless. (BTW, anybody have a $5 eBay gift card they'd be willing to trade for my $5 Amazon so I can get some cheaper screen protectors?) So how can I make sure my iPod is free of defects before putting on the screen protector? My original plan was to slap on my TPU case as soon as I take the iPod out and then put on my screen protector, but like I said, it will get ruined if I have to take it off and reapply it.
