so someone must have bluetooth installed on it and if its bluetooth 1.1 then everything that needs it will work with it ,but some devices need bluetooth 2.0 and there is bluetooth1.2 and 2.1 and 3.0 ...
so find out what you got and you know which devices will work or not
or simply try it out , if its not working you can always get a bluetooth usb dongle they are cheap to get ,if you really need bluetooth of course
i still prefer these old fashioned wires to everything like keyboard ,mouse ,ethernet,firewire,usb
