need help streaming data with UNO and SEEED GSM/GPRS V2.0

configuration:
-ios mavericks
-arduino uno
-seeed gsm/gprs v2.0
-unlocked , verified at&t sim card data (no sms or voice calls)

how stream voltage readings analog sensor onto web?

i'm using m2x.att.com api, i'm open , interested in other options--perhaps better support community.

this code i'm using:

code: [select]

#include "serialmodem.h"
#include "jsonlite.h"
#include "m2xstreamclient.h"

serialmodemclient client;
char m2xfeedid[] = "df60542f9f2ee9c1fed588320363b823";    // feed want post to
char m2xkey[] = "30700b29c45af8922ec95e659e5da7a0";    // m2x access key
m2xstreamclient m2xclient(&client, m2xkey);

const int sensor = 0; // selects input pin thermistor

int val = 0; //variable used store value coming sensor

void setup() {

  // note: analogue pins ,
  // automatically set inputs

  serial.begin(115200); // in tutorial 9600
  while (!serial);

  serialmodem.setdriver(driver_mtsmc_h5);
  serialmodem.setserial(&serial, 115200);
  while (!serialmodem.ready()) {
    serial.println("waiting modem ready..");
    delay(100);
  }

  while (serialmodem.getnetworkstatus() < network_status_roaming) {
    serial.println("waiting network registration");
    delay(2000);
  }

  while (!serialmodem.setapn("wap.cingular")) {
    serial.println("setting apn");
    delay(2000);
  }
}

void loop() {

  val = analogread(sensor); //read value sensor

  serial.println(val); // print value serial port

  delay(1000); // wait 100 ms between each send

}






i tried using following code test modem:

code: [select]

/*

example test if modem working correctly.

circuit:
* gsm shield attached (using digital pins 2, 3, , 7)

*/

// libraries
#include <gsm.h>

// modem verification object
gsmmodem modem;

// imei variable
string imei = "";

void setup()
{
  // initialize serial communications
  serial.begin(9600);

  // start modem test (reset , check response)
  serial.print("starting modem test...");
  if(modem.begin())
    serial.println("modem.begin() succeeded");
  else
    serial.println("error, no modem answer.");
}

void loop()
{
  // modem imei
  serial.print("checking imei...");
  imei = modem.getimei();

  // check imei response
  if(imei != null)
  {
    // show imei in serial monitor
    serial.println("modem's imei: " + imei);
    // reset modem check booting:
    serial.print("reseting modem...");
    modem.begin();
    // , check imei 1 more time
    if(modem.getimei() != null)
    {
      serial.println("modem functoning properly");
    }
    else
    {
      serial.println("error: getimei() failed after modem.begin()");
    }
  }
  else
  {
    serial.println("error: not imei");
  }
  // nothing:
  while(true);
}

and got "error: not imei"

i gave on m2x.  i've tried xively well, not going either.  i've got same setup you.  know though, .setdriver method in m2x code refers model of gprs shield different yours.
