Look at AT&T go! It wasn't very long ago we last told you about AT&T's continued 4G LTE expansion, and now the carrier has given us more to report about today. AT&T has turned on 4G LTE service in five new markets across the US while expanding service in others, so it's going to be a good day for a lot of people as far as mobile data speeds are concerned.
