I can do a model for you but depends on what detail you want. If you just want a case printed, its really easy as all you need is external dimensions, gradual change of shape, button placements and so on. I've got a captivate so can base it off that.
Might require some fine tuning but should be easy
. All youd have to do is show me photos of issues.
PM me if you dont find anyone else in about two weeks (currently bogged down with work)
