Were your reboots related to UMA or not related?

I think you're right about UMA seeming more stable after the recovery from the flooding. Maybe they were on hold with some update and decided to throw it in when they could blame downtime on the storm.

After first update to .184 several weeks ago, I had to coax it to connect to UMA on 2 occassions, but now I don't have to do anything. The phone does it by itself. Still has a hard time with some hotel wireless routers though.
