Consume SAP Netweaver Gateway Web service in Windows Mobile 6.5

Question

Hi All,
I am using Netweaver Gateway Webservice in Windows Mobile 6.5 platform. I know if need to make POST request, first i need to make GET for fetching CSRF token and then passing the CSRF token again with POST request to do the create operation. So i have used the below syntax. But it is always saying as 403 forbidden status while making POST request. I had successfully fetched CSRF token in my get request. Is there any help available for the below syntax?
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri("http://hostname:8040/sap/opu/odata/APLX/ST_GRRF_TS_01/Headers"));
            request.Credentials = new NetworkCredential("ddsdsdsd", "sdsdsdsdsds");
            request.Method = "GET";
            request.ContentType = "application/atom+xml";
            request.Accept = "application/xml,application/atom+xml";
            request.AllowWriteStreamBuffering = true;
            request.Headers.Add("X-CSRF-Token", "Fetch");
            request.KeepAlive = true;
            WebResponse response = request.GetResponse();
            string strcsrf = response.Headers["X-CSRF-Token"];
            string strcookie = response.Headers["Set-Cookie"];
            string pXml = @"<?xml version=""1.0"" encoding=""UTF-8"" ?> <atom:entry xmlns:atom=""http://www.w3.org/2005/Atom"" xmlns:d=""http://schemas.microsoft.com/ado/2007/08/dataservices"" xmlns:m=""http://schemas.microsoft.com/ado/2007/08/dataservices/metadata""> <atom:content type=""application/xml"">" +

                   "</m:inline>" +

                   "</atom:entry>";
            request =(HttpWebRequest)HttpWebRequest.Create(new Uri("http://hostname:8040/sap/opu/odata/APLX/ST_GRRF_TS_01/Headers"));
            request.Credentials = new NetworkCredential("ddsdsdsd", "sdsdsdsdsds");
            request.Method = "POST";
            request.ContentType = "application/atom+xml";
            request.Accept = "application/xml,application/atom+xml";
            request.AllowWriteStreamBuffering = true;
            request.Headers.Add("x-csrf-token", strcsrf);
            request.Headers.Add("set-cookie", strcookie);
            request.KeepAlive = true;
            request.AllowAutoRedirect = false;
            request.ClientCertificates = cn;
            //request.Headers.Add("content-type", @"application/atom+xml");
            //request.Headers.Add("content-length", pXml.Length+"");
            byte[] bytes = Encoding.UTF8.GetBytes(pXml);
            request.ContentLength = bytes.Length;
            using (Stream putStream = request.GetRequestStream())            {
                putStream.Write(bytes, 0, bytes.Length);
                putStream.Close();
            response = request.GetResponse();
Here the response in the last line always shows 403 forbidden status.
