So, remember how you said you hope they were installing backhaul? I'm getting LTE right now by the zoo. I flashed a 4.4.4 based rom on my GN3 yesterday and had 0 LTE on the freeway to work. Just now I found a build.prop tweak that gives you the "spark" icon and low and behold, my 3G went to LTE. Thought it was just the build prop tweak playing tricks on me, but I'm getting 5Mbitt download right now
