I don't know if this helps, but I wanted a heavy duty swivel clip full case for my 7100i. I went to Krusell and found there small wide case (

The back of this case allows you to slip it on a belt either horizontally or vertically in addition to using the swivel button. I harvested a couple of strong bu thin magnets from a dead hard drive, and slipped them into the belt loop on the back of the case. I how have a heavy duty case that covers the entire phone and has the sleep function.
