splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
When applied, it creates a rainbow effect. Most people say that it's only noticeable when the phone is off; however, if you have even a remotely dark background or are doing something that the screen isn't really bright, it is very noticeable. It works for the time being until PowerSupport releases their crystal screen protector in a few more days.
