Moshi iPhone 4 iVisor AG Screen Protector - WhiteProduct Review (submitted on July 14, 2012):
I had this put onto the screen at the AT&T shop so I don't know how easy it would be to put it on myself, but I love it! The texture of very comfortable and even after sweating a bit due to a run, your fingertips won't stick unlike other kinds of screen protectors.
It's priced at ~$20+ but it's worth it. If you get a screen protector for such an expensive smartphone, you might as well invest in a protector. One scratch and you'll regret not getting a good protector. The ink is a perfect shade and it almost looks like there is no protector. It eliminates glare from lights and fingerprints are barely noticeable.
Overall, I am satisfied :)
