Not many people like to type on an onscreen keyboard. Though iPhone's keyboard is decent enough, there will be many out there who will disagree with me. Apparently a guy from Japan didn't like it either and decided to take matters into his own hands. The result is visible from the image.
He took his jailbroken iPhone, hooked it up to a QWERTY keyboard, and modified the cable. Check out the video, and you can see what the above maneuver makes the iPhone look like, an outdated digital diary. Oh, and yes, it still doesn't support Copy-Paste.
