At first, Chris Pollock‘s hack to connect his iPhone to a computer’s serial port seems like a “because I can” sort of project, but in reality, it appears that it’s actually incredibly useful.
Why? Chris apparently works in IT, and as it turns out, a jailbroken iPhone armed with a serial port connector and many of Cydia’s console packages is a godsend for an IT worker: it’s an entire computer that you can just whip out of your pocket in a pinch to do some mainframe troubleshooting.
Fantastic. Now if only your could use this serial port hack to sync through iTunes.
