Just got an OEM case for my 8700r w/extended battery.

Am quite pleased with it since it works with both types of batteries, and has a magnet front and back so you can insert the BB either way (extended battery seems to work best face-in). Has a swivel ratchet clip as well. Magnetized closure on lid. Protective velvet-type fabric inside on both sides. Only negative might be the thickness of the overall package -- adds at least 50% to the thickness of the phone alone due to heavy duty leather, but compared to the Fortte Vertical it's not bad (see pics)
