Even though this Chicago coverage map shows coverage all the way down to Interstate 80, I disagree with it. It will eventually be like that, but I just made a trip to Chicago from Morris, IL and I had 4G LTE for about 10% of the trip. (I went all the way to downtown, Michigan Ave.) I understand they are ahead of schedule, but they shouldn't mislead people to think that down the street from where I live there is LTE. (literally 1 mile down the road, supposedly)
