Checking for lost GSM network

Hi!

I know how to initialize the GSM shield in the "setup" function waiting for "GSM_READY" return code.
Now, I think it's safe to check in the "loop" function too if the network is still ok; if the GSM modules loses the network I think I have to wait for it again and eventually use this information in some way in my application.
So, is it only a thinh of calling the 'begin' method again like in the setup and checking for GSM_READY??

Thanks!

This feature doesn't exist in current version of GSM library, but it's interesting to add it in future versions.
