Thanks for the update nindi.
I was assuming all along that I-485 and I-130 get approved within couple of days of each other. Interesting to note that I-130s are now being approved earlier, and I-485s still pending - eg: in your case, and in case of "nsrpd" (http://www.trackitt.com/member/nsrpd).
More interesting and coinciding is that you both applied on same date (9/24/2012), and got I-130 approval on same date (7/29/2013) !!!!
