Now you can use your iPhone 3G, 3GS or second-gen iPod Touch with an external Bluetooth keyboard. The catch is that your iPhone will first have to be jailbroken, or hacked to allow it to run unoffici al thir d party software.

The driver will be available “soon” in the Cydia store (the jailbreak App Store) and will allow you to pair and use an external Bluetooth keyboard with the phone, making it a very viable all-day computer. As long as you’re not writing huge articles, we guess.

The first iteration won’t let you use the keyboard just in any old applicatio n, though: You need to use it within the iPhone Bluetooth Keyboard Driver application itself. Luckily, there is a workaround: If you install another package, called Simulated Key Events, it should r oute the key-presses to any application you like.

We’ll keep a close eye on this and try it out upon release. Really, though, this is something Apple should build in. Sadly, it probably never will, due to the company’s in famously button-phobic boss.
