Recived email from USCIS
"on August 4, 2010, we mailed you a notice that we had registered this customer's new permanent resident status. Please follow any instructions on the notice. Your new permanent resident card should be mailed within 60 days following this registration or after you complete any ADIT processing referred to in the welcome notice, whichever is later. If you move before receiving your card, please call our customer service center at 1-800-375-5283."
I hope it means Approved.
