Doubt it's a screen protector. Probably one of those gelaskin type of things. It's not that great-looking though...if you you look closely, the lines aren't even completely straight. Makes it look like the white frame was drawn on freehand 😱
Gelaskin can make you an all white iPhone skin and then they also offer a screen protector that is the size of the screen instead of the entire front. That's probably as close as you will get.
