I am sure this has been asked but I searched in every form of the device I could.

Can a HTC6700/xv6700/ ppc 6700 be used as a BT keyboard, and perhaps mouse/pointer with the joystick?

I did find these as possibilities, would someone explain which may work, and if you have any experience with them.
