Just a quick heads up to others buying matte or 'privacy' screen protectors (mine is from PhoneDevil, they're really good quality btw), the ones made for the older iPhones will really dampen the sharpness and pop on the new Retina Displays on the iPhone 4. Also, the cutouts for the speaker and home button just about fit, but the front camera becomes fuzzy because its covered.
I'm willing to sacrifice these for now since I have no one to facetime with
and I'm a bit OCD about fingerprints and scratch protection which are dealt with. I'm just hoping a manufacturer produces an updated iPhone 4 version which won't have such a noticeable effect on screen quality. Damn you Apple for your making me accustomise to such an amazing screen so quickly
