About a year ago, a story circulated about a belkin case which actually ended up causing scratches on the iphone. They were apparently pulled from the shelves. However, I got a Speck pixelskin case(which gets fantastic reviews on Apple website) for my iphone and I swear the iphone went into the case absolutely blemish free. I pulled it out yesterday and discovered a small area where the glossy part had been ground away. It's essentially the size of a speck(perhaps that where the case got its name? lol) as well as a hairline mark on the chrome. Not a great big deal I suppose except I bought the case to prevent scratches obviously -- not cause them. I can't really figure out how a soft silicone case could have caused a scratch except that perhaps some grit got in between the flexible silicone and the phone surface and it moved around. It's not like there's grit in my pockets however. Does anyone have a case for your iphone that you suspect actually caused scratches?
