This hack isn't for the faint of heart. In fact, it's more a demonstration of Dr. Ralf Ackermann's technical badassery than anything practical. But its as good as it gets until Apple achieves a state of sanity and flips the switch on its Bluetooth stack to finally allow us the option of pairing a Bluetooth keyboard to the iPhone. The setup starts with a cobbled together Xbox 360 Chatpad and XBee wireless module. The good doctor then takes a Jailbroken phone (naturally) and attaches another wireless XBee module to the iPhone's jury-rigged serial port housed in an Akku enclosure. A work in progress, it will ultimately rely upon a VNC server running on the iPhone to feed keyboard input to any application of your choosing. See Apple, this is the corner of desperation that you've backed us into.
Update: Video added after the break.
