Since the iPhone's introduction at Macworld in 2007, a large number of people have wanted a tactile keyboard. So far, Apple has not obliged. So, one iPhone owner took the initiate to make his own iPhone keyboard. Using a bit of Ruby code on a jailbroken iPhone, this user is able to connect a Palm keyboard via a 30-pin Dock Connector. The end result is an iPhone with a tactile keyboard. While we can't vouch for the validity of this video, it does look like a cool hack.
