/*Note: this code is a demo for how to using gprs shield to send sms message, dial a voice call and
send a http request to the website, upload data to pachube.com by TCP connection, The microcontrollers Digital Pin 7 and hence allow unhindered
communication with GPRS Shield using SoftSerial Library.
IDE: Arduino 1.0 or later
Replace the following items in the code:
1.Phone number, don't forget add the country code
2.Replace the Access Point Name
3. Replace the Pachube API Key with your personal ones assigned
to your account at cosm.com
