No need to shy away from a leather holster if you want one. I have used the Blackberry-branded leather holster for a month and a half with no discoloration. If TMo doesn't have one, you can always pick one up at the AT&T store.
Prior to that I used the TMo-branded leather case, which discolored my BSE full body shield. (BSE also sent a free replacement.)
