Since the Thunderbolt 2.11.605.9 code update a week ago, my 3G data connection is dropping frequently for a minute or two and then the 3G designation reappears until it drops again in a few minutes. In other words, the 3G data connection has become very unreliable. Is anyone else seeing this happen? The voice connection appears to be fine, and so it's just the data connection that is dropping frequently. I am in a 3G-only area in southern Minnesota.
