Bluetooth is a short range wireless technology. For a PDA its primary use would be to sync with a PC. For cell phones, it can be used for things like wireless headsets. I think it can also be used to allow a PDA (or laptop) to use a Bluetooth capable cell phone to access the Internet. It is also used for wireless keyboards and mice. You would need a bluetooth adapter for your PC (or built in) to talk to a Bluetooth device like a PDA or cell phone.
