It happend to me too abci !!!
My company changed lawyers after I applied I-485 and my new lawyer submitted G-28 form,But,for some Strange reason INS sent RFE(for my EAD appl.) to my old lawyer(But, luckily she forwarded the RFE to new lawyer.
My 485 appl. got approved this monday and don\'t know to which address it was mailed.
abci, I wish you all the best and speedy approval.
