Good news for those wanting to use a physical Bluetooth keyboard with their iPhones: Now you can. The catch is that you'll need to jailbreak your iPhone and that input doesn't work outside of this particular app at the moment.
Apparently all you need to do is download the driver, Bluetooth Keyboard Driver, through Cydia, install the demo app, and let your keyboard connect with your iPhone. Simple as that. Anyone given this a test run yet? [Ringwald via Mod Your i]
