Vishal,
I think you should hear back earlier, at least that schools have gotten your info. I was told that the 20th mailing will go out no later than this friday, so yours should've went out about two weeks ago. They must be WAAY behind, though. I had a correction to send in, and was told it would take two weeks to get to schools. If in fact it gets sent out this week, it will be five weeks! I'm afraid this may have killed my chances for early interviews, as most schools won't look at my app until they receive the corrections.
