Hi. I'm just wondering if I need to use an additional case for my iPhone 5 in white (I'll get one in few weeks). I'd prefer not do it, because I love 'naked' iPhone design, but there's my question: does white iPhone 5 get scratches or something like that on it's backplate easily? For example: after putting it on table etc.? My previous iPhone 4 does and it wasn't good for me. How about it, guys?
