splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
Bought this screen protector based on all the awesome reviews it has received. It was a complete waste of money. I tried to put front cover 3 times and every time it still has air bubbles that drove me nuts. I used all tips and suggestions I could find on here, but it was useless. Did not even tried to put back cover, since there's no use for it for most people. Should have bought 10 packs for $0.99 each instead of this over priced over hyped junk. Never had problem with other screen protectors.
