Http connection not working on phone

Question

Hi i am trying to connect to a http server using the new nokia n95 phone with T-mobile web and walk(Unlimited 3g internet access)
on the emulaor and on the phones wifi connection, it works. But when i try connecting to the server using gprs/3g it doesnt. The response code never equals to OK . here is my code below:
I know it is not working because has soon as the program makes an attempted to connect, the root.notifyDestroy() closes the application as i expect it too
server = (HttpConnection) Connector.open(url);
            server.setRequestMethod(HttpConnection.POST);
            int rc = server.getResponseCode();
            if (rc == HttpConnection.HTTP_OK)
               is = server.openInputStream();
            else
                root.notifyDestroyed();
                 Alert alert = new Alert ("Error");
                alert.setString("Error, server is down");
                alert.setTimeout (5000);
                Display.getDisplay(root).setCurrent(alert);
                throw new IOException("HTTP response code: " + rc);
            }

I had all sorts of strange problems getting http connect to work from phones. Most of my problems were resolved by adding every single header I could find that tells the carrier's gateway to leave it alone. Try adding these headers to the connection from the phone, and the response from the server:
                    connection.setRequestProperty( "User-Agent","Profile/MIDP-1.0 Configuration/CLDC-1.0");
                    connection.setRequestProperty( "Content-Type", "application/octet-stream");
                    connection.setRequestProperty( "Content-Length", ""+(allContentToSend.length));
                    connection.setRequestProperty( "Cache-Control","no-store");
                    connection.setRequestProperty( "Cache-Control", "no-cache");
          connection.setRequestProperty( "Pragma","no-cache");
          connection.setRequestProperty( "Cache-Control", "no-transform");
          connection.setRequestProperty( "Connection", "Keep-Alive");
          connection.setRequestProperty( "Proxy-Connection", "Keep-Alive");          
The content-type will depend on what you are sending. octet-stream is for binary data. If you are just encoding parameters in your POST you may need something else like "application/x-www-form-urlencoded".
The content-length is obviously dependant on what you are sending. The rest of the properties simply tell whoever is transporting the request to leave it alone.
TEMP_MOVED sounds like a redirect or some odd thing. Maybe the carrier is caching the response, and you are actually getting something unnexpected.
Hope this helps.
