Bluetooth wireless is total different from lan A,B,G wirless cards. But if you got a bluetooth adapter and installed the bluezutils then you should be able to make the cell phone act as a modem. May require extra services from cell phone provider. You can check at http://tuxmobil.org/phones_linux.html
to see if your phone is listed and see what can be done with it.
For a bluetooth adapter I have used both a kensington model 33348 and a Belkin model f8t001
For your wireless card check out the HCL section at the top or to the right and see if listed in there. Also you can check with other makers of bluetooth adapters there as well. A wealth of knowledge in there.
