I am looking for a battery cover that has some texture to it. Something like the Rock Quicksand case, but as a cover only. Or something rubberized would be cool. I am just looking for something to keep it from sliding out of my hands. Not for Protection. I have an S-Line case for going out. Considering a carbon fiber sticker option, but i would prefer an actual cover. CNN.CN has a leather one that looks promising, but it is an international site, and though it is trusted, i would prefer to deal with someone here in the US. Thoughts?
