Forms Services Data Source Error using Mobile Device Emulator

Greetings -- hopefully someone can help me out. I am trying to design an InfoPath form for use on a mobile browser. I have followed the instructions at the following link, to the letter:

http://msdn2.microsoft.com/en-us/library/bb251745.aspx

Here are the basics of my environment:

- Stand-alone single server installation of MOSS 2007 on Virtual PC 2007

- Simple form template published to a library in MOSS, as well as uploaded and activated for my site collection through MOSS Central Admin

- The template accesses an external data source (SQL Server 2005) within the form

If I look at the form in a regular browser, everything works perfectly. If I look at the form in the Mobile Device Emulator (it is "cradled", and I have a good connection -- I can even browse external web sites), I get a series of the following errors after the login page (one error for each connection in the form's data source):

Warning: There has been an error while processing the form.

Details:

An error occurred accessing a data source.

I have tried just about everything I can think of to work around what the issue might be. I have tried it using Windows authentication and SQL Server accounts. I have tried it using a direct connection to SQL Server, and I have written a web service to extract the data. All permutations give the same result -- works fine in a regular browser but fails in the Mobile Device Emulator.

Any assistance would be greatly appreciated.
