I am having problem with HTTP POST on series 40 phones. 7210, 6800 randomly give: "Unknown Error Ind(0x21, 0x60)" , 6100: "Unknown response" or "connection lost" error message and then the application throws Exception. This occurs randomly, it may happen at the first HTTP POST request, or after several times succussful POST. When this happens, the request actually does not hit the server.

What might be the problem? Is it possible to be our code problem, or just because WAP gateway is doing something? Any suggestions?
