I'm another one.  I got a message about an update being available, tried to download it and it failed on install.  I'm still on 2.3.5.  I was really hoping for ICS since they have been saying in Q1 2012.    I'm also on an unlimited plan so that may have something to do with it.  I still quite bothered that I'm being throttled when I get to 2GB.  It doesn't really slow down, it stops.  If it went to 3G speeds, I'd probably be able to accept that, but once I go over the 2GB, I can't do anything.
