Yes I am still waiting...they received my application May 24th. I send a service request twice and they send this back..."The status of this service request is:

U.S. Citizenship and Immigration Services (USCIS) records show that your case is currently pending adjudication. However, we have had to perform additional reviews on your case, and this has caused a longer processing time."

I don't know what additional reviews they need to perform since my record is clean but it just seems like a generic message they send to everyone...
