splash Masque Clear Screen Protector for iPhone 4 4G  4S AT&T and Verizon (3-Pack + 2 Bonus Back Films)
These are the best screen protectors I've used so far. The front is absolutely clear- no anti-fingerprint film to blur the retina display.  The bonus two back protectors have an anti-fingerprint matte finish, which is just what you want on the back of the phone, it keeps it looking clean.  Very easy to apply with no bubbles.  Includes a cleaning cloth.  Tip: if any dust gets under the film, use one piece of scotch tape to lift up the film and another to grab the piece of dust- no bubbles.
