I got a hit on my phone last night according to my LTE record. I traveled across the hart bridge down university Blvd then down Atlantic to the Walmart on Kernan. So somewhere on that stretch my phone connected to LTE.
Also I connected to a site for the first time without cycling airplane mode. I updated my EVO LTE to jelly bean and it looks like HTC increased the scan times. I'll test the connectivity when I go back to work Tuesday and connect to a LTE site.
