Using the GSM_Shield_Test sketch the returned number and message text are null from GetSMS - looking into this it seems the retrieve message command needs the position to be sent as a string rather than as the value itself. I'm not sure if this is the best arduino way of doing this, but a sample fix is as below:

char GSM::GetSMS(.)
...
//send "AT+CMGR=X" - where X = position
mySerial.write("AT+CMGR=");
char posArray[4];
itoa(position, posArray, 10);
mySerial.write(posArray); // was : mySerial.write((int)position)
mySerial.write("\r");

Hi,
I really appreciate you library so thank you very much!
in you sms.cpp it requires a char string for both the phone number and the message.
"
char SMSGSM::SendSMS(char *number_str, char *message_str)
"
Im hoping to send some dynamic information like temperature and other things
currently my temperature is a float.
is there any way of amending the sms.cpp to allow for more than just char strings?
this is where in at with my arduino code- its just a snippet:

if(!strcmp(smsbuffer,"Temp?")){
delay(dht.getMinimumSamplingPeriod());
float humidity = dht.getHumidity();
float temperature = dht.getTemperature();

      Serial.println("Getting temperature");
      Serial.print(temperature, 1);
      Serial.print(" degrees C");
      Serial.println("");

      sms.SendSMS("+614********", (temperature, 1) );
 Serial.println("\nSMS sent OK");

     delay(10);

When I send the SMS. the Text from SMS is not display at serial screen... for serial communication I'm using baudrate 57600, and for SIM900 is 9600
