Relays via mobilephone

[lobster]

Hi!.
Do you know companys that produces relays to connect to a mobilephone, or a relay module with GSM built in?

I want to recieve status and input of the relay and to be able to send commands to the relay.
GPRS/ would be the ultimate protocol to work with.

I looked at http://www.rfsolutions.co.uk/acatalog/GSM_Telemetry.html but it's to expensive

check the mp3car.com forums, several people use cellphones and pagers to unlock their cars now, I am pretty sure I saw them mention several affordable products, but I don't remember the details. If you can't find those threads, I will try to find them later today when I have more time.
