Ok where I live there is no 4G..
This past weekend I went too visit relatives in PA. They live in a rural area like I do and not only did they have cell service it was 4G.
8mb to 12mb download on a weak signal. It was excellent. As fast as WiFi at home.
When stopped for gas on the trip in a city I don't know the name of it was 16 mb download.
Overall a nice preview of what it will be like in a couple years when we get LTE in my neck of the woods.
