Just wanted to update everyone on 4G in the Jamestown, NY area (in the Buffalo market).
4G was spotty, at best up until about a week ago, when both speed and signal strength went WAY up (so much so that I get better speed from 4G than from WiFi in my own apartment). Some areas of Lakewood (just to the west) are also 4G, but the network there is acting the way downtown did through much of last month, so I expect it to be up and running full-time by mid-January. Areas to the east and south of the city, however, remain stubbornly 2G, with a few spots of 3G, as is a small gap between Jamestown and Lakewood on Fairmount Avenue. As I haven't been very far north of downtown lately, I am unable to report about the area near and north of I-86.
If you take a look at the map at Sensorly, you'll see a nice blob of purple. Probably 90% of that is from my phone.
I'll keep everyone advised as the network expands.
