Me too, and I am also in Minneapolis. I figured during the day at work it would "correct itself". I pulled the battery, messed with the network settings, deleted a couple apps I installed yesterday, all to no avail. Figured I would see if anyone else was suffering. On HoFo, people were told by TMobile (my carrier) that it affected everyone West of the Mississippi.
T-Mobile told me (when I called around 7pm EST) some cities are currently experiencing an outage, including here in Columbus OH and in Pittsburgh. My TMO BB has been stuck on GSM all day. I have also had a couple users (from the Columbus area) call me with the same issue.
