Does anyone have any suggestions about cases that are easy to put on and east to take off with out damaging the iPhone itself? The reason I ask is because I doubt I will use a case unless I go out of the house. If I am at home or even at work I will probably keep the case off because I love the look of the naked iPhone. So, if anyone has any suggestions of some barely there cases or easy to put on take off cases that would be awesome. Thanks!
