Could someone please help to find out the exact agent string for the latest symbian whatsapp client.!! I tried changing 2.6.61 to 2.6.99 and did not help. Then I saw on whatsapp site version is listed as 2.7.1, and even that did not help and I still got a message from server once about upgrading. I dont ming the server messages as such, but after getting the messages from server, wazapp cannot receive any more messages, looks like communication breaks after the server message, until you restart wazapp.
