I am in the same boat, my RFE was replied on 6/9/08, and no updates since then, not even update the USCIS received my documnent, then my lawyer called then on 7/15, USCIS asked her to call back in two weeks. on 7/31 she called them back and they said sometime officers sent their cases to supervisors and they have 500+ cases to look at, so now USCIS asked us to call back in 30 days, so I am crossing my fingures to get something by 8/31 or my lawyer will call them back on 9/2 (FYI - My Lawyer is FDBL)
