Mark Dain I think I know the answer to this but ... is there a way to recieve text messages via an API? Not for an arbitary number but for mine; the number tied to my SIM card (in my iPhone). I'm with Three but I imagine the answer is no from every carrier.

Martijn AFAIK unless Three offers you an API there is no way, because Three is delivering text messages to the right SIM. Any chance they offer duplicate SIM cards, e.g. to use in cars? I wonder if you can get access to your text messages with one of those hooked into your home server with a USB SIM reader. Some Huawei dongles come with GUI software that allow you access to text messages, I know for sure.
