Well just got my sparkly brand new iPhone 5 (white). With my 4 I used a screen protector and case from the start, but took the screen protector off after a year. It's still virtually pristine. DID keep it in a case of some sort. Really didn't like the feel of a screen protector, and am always very careful with my phone. Now with my new phone I am minded to not use a screen protector but just keep in case - Case Mate protector indoors and then when I take it for an outdoor trip, a leather slip case (have ordered a Joli). Any thoughts?
