Finally got my update, I have had it almost 20 hours and I am trying to figure out what it was supposed to do. Screen orientation issue is fixed but that was the least of my problems. I am still operating at -115 dbm. So signal strength issue not fixed. Bars do display differently but the dbm strength (the real indicator) is exactly the same. Call quality has not improved at all, in fact it may be worse. It has a different sound that is more muffled instead of the robotic sounds. Still have tons of background clicks and squeals etc. I am trying to patient as I have been for the last almost six months but it doesn't appear that the update has helped in the ability to use the GNEX as a phone. I'd love to hear from others, what did 4.0.4 do for you?
