BlackBerry Charging Holster 

RIM seems to be on a bit of a patent kick lately (more than normal at least) and this time around has landed one for a phone-charging holster. The device is pretty much a standard phone holster that has a second battery for charging your phone. When your phone is in the holster, it would be charged from a second battery so you would always have some extra juice on the go  -- of course that means charging two devices instead of one before you head out. We've seen some third party options that are very similar, but this could be something cool in the RIM arsenal.
