+ SMS receiver
+ 
+ This sketch, for the Arduino GSM shield, waits for a SMS message 
+ and displays it through the Serial port. 
+ 
+ Circuit:
+ * GSM shield attached to and Arduino
+ * SIM card that can receive SMS messages
+ 
+ created 25 Feb 2012
+ by Javier Zorzano / TD
+ 
+ This example is in the public domain.
