Yes, Today i checked the status of my case at USCIS after denial and they said that:-
On September 20, 2011, the appropriate American Consulate or port of entry was notified of the approval of this case. Please contact them directly if you need more information.
For approved applications/petitions, post-decision activity may include USCIS sending notification of the approved application/petition to the National Visa Center or the Department of State. For denied applications/petitions, post-decision activity may include the processing of an appeal and/or motions to reopen or reconsider and revocations.
I think u didn't read this post full from 1st page to last page anyhow u can read about the denial reason here:-
