I just checked the Apple iPhone Dev Center and it says that my application is in the following state:
Company documents needed
. Requested documents must be received to proceed with enrollment
I've sent them in (Monday), but I'm guessing that this is the standard message they post until they've actually processed the documents.
Regardless, I think things are still moving forward. Better than the "If you've already applied, we're processing your application" message it used to have. :)
