When I had Auto On/Off enabled, my BB used to override Turn All Connections Off and start bleeping and syncing at 06:30, causing alarm and paranoia amongst flight attendants (who tend to be BB non-believers) as well as some interesting data charges from countries I'd never planned to visit.
So now my pre-flight checks include disabling Auto On/Off, my BB stays silent, and everyone seems happy.
