Bluetooth support works quite well on my Nokia 3110c for obtaining an
rfcomm device for GPRS dialup, and for doing strange things with HID
emulation to remote control my eee :P

There's a *tiny* USB bluetooth dongle for about ?7 on Scan:
I have one of these and it is literally plug and play on recent
kernels. Not tried it on anything older than 2.6.24 that I can recall,
but I don't think standard Bluetooth device support has changed that
much in recent years.
