    Mobile 6 device causing Error calling web service

    Hello All,

    we have a Pocket PC .Net Compact Framework 2) application, that calls a Web
    Service located within the Company network,
    which is also accessible via https from outside (the internet). This
    application usually communicates with the server
    via cellular carrier connection, GPRS.

    The application works fine with our Windows CE 2003 SE and Mobile 5 devices.
    Running the same application on a Mobile 6
    device causes the following error ONLY when trying to connect to the
    webservice from outside the company's network (in other
    words via GPRS):

    "Unable to read data from the transport connection.".

    The call to the webservice within the network is successful.

    Until now, I was unable to figure out and understand why this error comes up
    only via GPRS and only using a Mobile 6 device.

    Any help or advice would be greatly appreciated.

    Thanks,

    Michael
