I'm not willing to call it "fixed" yet, but it's not been nearly as bad for me, either, over the last couple of days. My wife has a razr and just did the OTA to ics. She says her problem is solved. It looks as if Verizon has been doing some updating. I would say it's in preparation for the RNC, but I had big problems in Miami, too. It was a problem over a large area.
The question I have is: If an upgrade needed to be done, 1) why was everything OK until they started upgrading - then it went to crap? And 2) If they knew what they needed to do, why did it take so long to do it?
