Unveiled today at E3, the X-tra Fun Bluetooth module for the GameBoy Advance SP will go on sale around Christmas 2003 for $49, more info at ExtremeTech.

The Bluetooth module will require a separate cell phone or other device for Internet access, although it can share a Bluetooth piconet with up to seven devices. Those devices, if connected to GameBoys, could also use the Bluetooth network to play games which X-tra Fun plans to provide, Kramer said.
