There may be a reason why we're not getting the update in Chicago.I can't speak for the whole city (many, many towers), but I was having a problem with my air card not connecting to the Wimax 4G network. After contacting CS, I was informed that it had been down in my area for a couple of days. Without being too committed, my rep told me that I would see a huge increase in speed within the next few days (by Monday, 730). Although she wouldn't definitely confirm, it sounds like Network Vision and LTE will be rolled out in this area. It has already been rolled out in some of our western suburbs and NW Indiana. So the latest update may be held back until then. We can only hope.
