Thanks for the insight. I too have noticed that 3G in Chicago is really bad. I can't say for sure if the system is overloaded but its spotty at best, at least from a Data point of view. When my phone bumps into 3G for whatever reason (elevator, subway, basement, poor 4G coverage, etc) and the 3G kicks on data functions start to time out and fail pretty consistently. Things work OK on 4G WiMax in Chicago now, but coverage gets real spotty once you leave the city proper, its ever terrible at both airports. Im looking forward to the arrival of 4G LTE, from what I have been reading and hearing in the rumor mill, if I had to guess when LTE is really "here" in Chicago.....Id say sometime around the end of the year, November or December.
