I remember when the 3G came out we got those cleaning cloths to wipe off smudges and grease. Now, with the new iPhone 5, finger prints are no more! This metal backing gets NO smudges or finger prints. The oleo-phobic coating is really good (until it wears). Let me just say, I do keep my hands washed and only use non oily soaps with no moisturizer or creams to help keep them dry. Thanks Apple!
