Here is a good overview of OBD:

I'm not sure about the iPhone products, but I imagine they require a special cable with one end having the OBD connector as described above, and the other having the 30-pin (or now lightning) connector for the iPhone.
Actually - it looks like a number of devices have a wireless sending unit that connects to the OBD port, and the software resides on your iPhone or iPad and connects wirelessly to the OBD reader.
