I want to know where to source that blackberry jog-wheel. I can't seem to find any PCB-mounted jogwheels that both (a) rotate in a plane parallel to the board and (b) are meant to be operated by touching the edge of the wheel (rather than its face, like the dial on the Sansa Fuze) and (c) don't cause the depth of the device along the axis perpendicular to the PCB to become huge (i.e. like a knob-style encoder without the knob).
