Most proactive boards work by splitting what the computers output is to the monitor so unless your phone has a VGA output (or DVI) its a lot harder. Even if you get over that hurdle, whats the point? At the most you could POSSIBLY control the mouse pointer...woo hoo
Good luck though...
Oh, and we cant give help on how to "hack" (for want of a better word) either..
I doubt it. It's largley on a ActiveBoard >> Laptop basis. There is an Infrared revicer on the board... BUT, the proberbly wouldnt control the mouse-input - as the Pen used on the board isnt infra-red based.
