Where to find a good tutorial about Icomsat 1.1

Hi, I was wondering if anyone knows where I can find a good tutorial about the sim900 based Icomsat 1.1, cause I'm a total newbie and I really can't figure out how to use it. My project was to use it with an arduino uno to send the status of some sensors via sms.

The link in my signature isn't specifically about the IcomSat shield but the principals apply.
