So does anyone know if there's a conversion chip in there or whether the standard iPhone connector has a serial pin on it. I seem to remember someone hooking up a GPS to the iPhone 2 and plugging serial straight on. There are already a number of breakout plugs out there, so I'd be surprised if this opens up radical new innovation. As a side note, other people have used the audio jack for I/O, like the iPhly Remote Control or Square

It has serial on the connector. It is 3.3V TTL level so you will need a converter to turn it into 'real' serial. If you jailbreak a device you can access this port without any problems and do cool stuff. Just be sure to properly buffer and convert the signals. You don't want to kill your device. Sparkfun sells connectors in a breakout board. So does DealExtreme I think.
