We have a great thread going in the Carrier (Sprint) forums specifically on Chicago land area for the Sprint Network Vision upgrade, stop on by and take a read.
i think the LTE on this phone works better than wifi. I don't get data drop outs while downloading things like movies/videos. the wifi, i would constantly come back to see things fail to finish, even with wifi always on/better performance. it didnt matter. but I'm enjoying the lte speeds
Yep, me too! I've noticed that I've had a 4G signal in parts of Rogers Park, Evanston and Morton Grove. Download has been a little slower than my Comcast/Xfinity WiFi, but upload is significantly faster.
