joondad,
If you ever suspect that your i485 might be revoked for any reason, I'd like to advise you not to change jobs. My case was also denied due to the revoked I-140 as urguest's. I had to go out the states to get a new H1 visa, too. I filed a motion(MOTIC) and it was approved more than a year after it was filed with Congresswoman Anna Eshoo's help. Then, RFE, 2nd FP, and more waiting. Better not get into unnecessary troubles.
