Arduino & GSM

Hello,

Can someone provide some guidance on how to communicate with an arduino via a GSM shield? I'm looking to simply turn on and off and LED by texting the arduino. Also, it would be great if the arduino would text me back telling me the status of the light (i.e. "The light is on").

Any ideas?

Thank you.

Did you look already at the examples in the GSM library?
