I know this directly from a Sprint rep ... the test tower there is on the corner of Morse Rd. and Tamarack Rd, and yeah, that covers the Easton area. I had 4G when I was at Menard's out that way the other day, did a speed test and got 13mbps down and 7mbps up. A friend of mine reported getting some LTE access in Grove City as well, so there may now be a couple of pockets in town.
(and yeah, Sensorly is all over that!)
