+ GSM Scan Networks
+ 
+ This example prints out the IMEI number of the modem,
+ then checks to see if it's connected to a carrier. If so, 
+ it prints the phone number associated with the card.
+ Then it scans for nearby networks and prints out their signal strengths.
+ 
+ Circuit:
+ * GSM shield 
+ * SIM card
+ 
+ Created 8 Mar 2012
