splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
Very good quality screen protector.  I am ordering another set for backup.  I used all three before I applied one that didn't have lint under it.  That was my fault, not the screen protector.  Can't beat the price to get a 3-pack.  Slight rainbow effect when the screen is off, but not really a big deal.  Overall a great protector at a great price.
