I seem to remember that some providers had some sort of SMS/MMS<->Email setup such that you could email a [phone number]@[provider.com] address and the recipient would get an SMS and be able to reply. Maybe something like that?
It might have been something like that. I remember there being a phone number@something, but I’m not sure if the something was flickr, blogger or something the phone company provided, or perhaps I found some 3rd party mms to rss gateway. Can’t remember exactly, only that I had it working.
