got some progress but hit another barrier 
I manage to run a server for a few seconds and then it just hangs while waiting for data.
the following is the my Server code:
#include <inetGSM.h>
#include <SoftwareSerial.h>
#include <SIM900.h>
#include <LOG.h>
//To change pins for Software Serial, use the two lines in GSM.cpp.
//Simple sketch to start a connection as server.
InetGSM inet;
char msg[50];
int numdata;
char inSerial[50];
int i = 0;
boolean started = false;
long lasttime = millis();
void setup()
{
//Serial connection.
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower
if (gsm.begin(2400)) {
Serial.println("\nstatus=READY");
started = true;
}
else Serial.println("\nstatus=IDLE");
if (started) {
//GPRS attach, put in order APN, username and password.
//If no needed auth let them blank.
if (inet.attachGPRS("sphone", "", ""))
Serial.println("status=ATTACHED");
else Serial.println("status=ERROR");
delay(1000);
//Read IP address.
gsm.SimpleWriteln("AT+CIFSR");
delay(5000);
int i = 0;
while (i<20) {
gsm.SimpleRead();
i++;
}
//TCP Server. Start the socket connection
//as server on the assigned port.
Serial.println(msg);
delay(5000);
if (inet.connectTCPServer(80))
Serial.println("status=TCPSERVERWAIT");
else Serial.println("ERROR in Server");
lasttime = millis();
}
};
void loop()
{
if (started) {
//Check if there is an active connection.
if (inet.connectedClient()) {
//Read and print the last message received.
gsm.read(msg, 50);
Serial.println(msg);
}
}
else {
serialhwread();
serialswread();
}
};
void serialhwread()
{
i = 0;
if (Serial.available() > 0) {
while (Serial.available() > 0) {
inSerial[i] = (Serial.read());
delay(10);
i++;
}
inSerial[i] = '\0';
if (!strcmp(inSerial, "/END")) {
Serial.println("_");
inSerial[0] = 0x1a;
inSerial[1] = '\0';
gsm.SimpleWriteln(inSerial);
}
//Send a saved AT command using serial port.
if (!strcmp(inSerial, "TEST")) {
Serial.println("SIGNAL QUALITY");
gsm.SimpleWriteln("AT+CSQ");
}
//Read last message saved.
if (!strcmp(inSerial, "MSG")) {
Serial.println(msg);
}
else {
Serial.println(inSerial);
gsm.SimpleWriteln(inSerial);
}
inSerial[0] = '\0';
}
}
void serialswread()
{
gsm.SimpleRead();
}
and this is the output to the Serial:

Can anyone PLEASE help me figure this out???
