splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
This screen protector was difficult to apply.  I have yet to apply it without any dust or air bubbles.  It seems to collect smudges and fingerprints.  I had the Zagg screen protector before this one and I think that one was much better...although I'm still searching for a screen protector that I like.  I wouldn't recommend buying this product.
