Ralf Ackermann has posted a very cool video in his blog that shows an iPhone is paired with an Apple Bluetooth keyboard (this should work with other bluetooth keyboards, as well). Earlier, I’ve reported a hacked application (not yet release to public) to use bluetooth to transfer files between other bluetooth devices. This time, it’s great to see developer to achieve another great milestone that opens up opportunity for bluetooth keyboard connection.

Connecting iPhone with a bluetooth keyboard is one of the most-welcome features. I’ll enjoy the way that I can blog or jot notes via a portable bluetooth keyboard. This hack is really cool. However, it is not yet available to the public. And the developer doesn’t disclose any timeline for the public release.
