i'm looking for a hard case that doesn't scratch the back/side of the iphone when you put it on. I had this case http://ep.yimg.com/ca/I/exchangecellular_2065_1819361075 but when i took it off the back of my phone was scratched and also the metal sides, not to mention leaving a mark on the screen protector.is there any hard case that has a soft or silicon like inside? i would appreciate any suggestions.
