I'm in Manhattan every day and drive through mid town and never seen 4G. I went over to Cruger and Burke and sure enough enough 4G but the speeds were horrible.. The download was like 800kbps and it was so slow the upload didn't even start. When I was on cross Bronx I saw a 4G spot as well didn't get to test speed though as I was driving.. I hope the speed I got o, Cruger and Burke isn't going to be. I get 1.5 - 2.5mbps down in Manhattan on 3g and about 1.5mbps where I live. I'm right off Boston road in Pelham Manor right before fairway
