So I'll be getting an iPhone 5 next week to replace my current iPhone 4. I've been using PowerSupport screen protector on the latter since the beginning, but have been contemplating not putting anything on the front glass this time around. (I'll be putting the phone into iSkin Claro though). I keep hearing people say that the front glass won't scratch blahblah, but is that really the case? I usually never put my phone into the pocket with other things, so it's phone only. Is it safe without a screen protector that way? Or will there eventually appear small scuffs etc on the screen?
