Just wondering, is there actually any advantage of a screen protector? I mean, the iPhone screen is near invincible to scratches... and screen protectors can't pretect it from impact anyway. A cheap screen protector would probably scratch more easily than the iphone screen itself. The only thing I can think off is protecting it from spills but besides that I can't think of anything else...
By the way, I tested the screen myself by running a craft knife blade down the screen and it didn't scratch in any way... (just to see if the claims are true

)
