Having recently bought a new iPhone 3GS and being overly protective of it, I was constantly wiping the surface to get rid of the fingerprints - and then I discovered the PhoneDevil privacy screen protector. I wasn't too keen on it to start with - air bubbles appeared and the screen is not as clear and defined as it is without the protector on - but I persevered.....and the air bubbles disappeared, the fingerprints are barely noticeable, the screen clarity is absolutely fine and nosey-parkers are kept at bay!
Top dollar product for a bargain-basement price - highly recommended.
