One of my friends who knows more about this is when this usually happens usually LTE will be following some time soon after. But Im not holding my breath till I see it for my self.
I know something is up because when I was in town yesterday between 9am and 3pm i was having all sorts of data issues like they where either working on towers or testing stuff on them. Had some data issues while in town last night as well but not as bad. Then this morning my connection to the towers were pinging all over the place to one tower to another and going in and out of 1x and 3g. So lets hope they are working on the towers.
