There are quite a few iPhone owners who would like the ability to use a Bluetooth keyboard with their iPhone, now you can if you own a jailbroken iPhone.
One clever hacker has created a driver that can be installed on your jailbroken iPhone, once it is installed all you need to do is pair your iPhone with your Bluetooth keyboard.
This iPhone Bluetooth keyboard driver fills this gap. It is based on the open-source BTstack project, a Bluetooth stack designed for embedded devices where resources are scarce.
This driver runs on the iPhone 3G(S) and all iPod touch devices with Bluetooth support. It is unclear yet, if it works properly on the iPhone 2G. It will be available via the Cydia Store soon.
The iPhone Bluetooth Keyboard driver will work with the iPhone 3G and iPhone 3GS you can find out more details about it here.
