GSM

Hello to all.
It is the first time I write on the forum.
I'm just starting out with arduino. I have to develop a project for my thesis and I need to send and recive text messages (or data) from one shield GSM / GPRS shield v2.0 to another shield GSM / GPRS v2.0.
Can anyone tell me how to do or suggest me some examples?
Thanks

I've seen examples doing exactly that, and I'm sure that if you used Google you would see them too.

Can anyone tell me how to do or suggest me some examples?
