140 application help?

I checked my 140 application status online and got this:
---------
Application Type: I140, IMMIGRANT PETITION FOR ALIEN WORKER

Current Status: Case was shipped to the Department of State for visa
processing.

On July 17, 2007, we shipped this approved or re-affirmed case to the
Department of State for visa processing. For more information, please
contact them directly.
-----------
Can anyone tell me what it means? Approved or not?

Thanks.
