I have had my iPhones naked since day one. My 3GS dabbled in a Zagg invisibleSHIELD for a while, but I eventually tore it off. My 4S tried a Desmay Slight for a while, but it eventually met its demise. Outside of those two trials, I have kept my iPhones naked. Scratches don't really bother me, but I am still careful & my phones never looked all that bad (thought the 3GS was looking pretty rough on the plastic back towards the end of its 2 year run). When I get the 5S, I doubt that I will get a cover for it at all & just let it run around naked again. What about you?
