Its still very hit or miss. I am about 15 miles north of the airport and its on most of the time, but other places around town, very little coverage still.
there is one tower close to me in Lewisville and one in The Colony...I hear Hurst is pretty stable......havent heard of any other spots...towers seems to have a mile radius at best
I was at the State fair this last weekend. Had LTE the whole time. There is a tower right outside the Cotton Bowl. Had no issues and is was nice to be able to load pics of the fair so quickly to facebook and send to friends.
