The Power Support Anti Glare screen protector the Apple Store sells is my favorite. It is Static Cling so there is no residue. The package comes with 2 in case you mess the first one up. I had this screen protector on my 1st gen iPhone and bought it right away for my 3G. The anti-glare has a light texture to it that feels nice and doesnt show fingerprints. They also make a crystal clear model.
