The same advice was given at a San Diego Software Industry Council presentation that I attended last Thursday. Alex Shah of Facedouble.com shared his development and store experience. As well as the phone number.
(408) 974-4897
(800) 633-2152
From outside of the U.S., use the first number.
You can view the slides used in the presentation, and a video of the presentation here. (It's right in the left-hand column of the home page.)

The only thing in this presentation that I don't fully agree with is "don't drink the kool-aid". Alex side-stepped Objective-C by writing largely in Javascript/JQuery (and PhoneGap) using WebKit.
Anyway, Alex's experience involved 3 months of waiting to have his business developer agreements completed. He said that he never received any request for corporate papers (and so a lot of that time was unnecessary waiting for an email that never arrived), and strongly urged people to FAX the documents proactively, and to contact Apple at the number above if things bog-down.
The FAX number:
408-974-1053
He gave out another FAX number and emails for the specific case of dealing with banking (the SWIFT code for his bank, Union Bank of California, failed to validate) - you'll find those in the slides.
