splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
I've installed several screen protectors on my iPhones in the last three years. Some were great, and I was able to achieve a perfect instaalation. This one is terrible. It doen't fit 4s phone precisely. Has a tendency to leave bubbles. Has multicolor glare under incandescent and fluorescent light - I don't recommend.
