USIW, Minneapolis wireless vendor, has mailing lists you can sign up for. One is for general information on deployment progress and rollouts. So far they have not provided much information. The scheduled deployment dates have been slowly changing over the summer with nary a word about it on their list.
The other list is to keep customers informed on upgrades, maintenance, outages, etc. It’s intended only for USIW customers. They accepted my subscription request so I’ll see if I get any emails. (I am not a customer.)
