FYI: The setting to turn these off are in Notifications -> Government Alerts. The piercing siren seems a little excessive for Amber alerts...and doesn't even go quiet in silent mode. It's the default option on iPhone 5 AFAIK.
I can't wait til a movie theater erupts with the sound during a suspenseful moment in the film. You can't be embarrased about your phone making that noise if everyone else's did too, right?
Perhaps that's why they ask you to turn them off before the show and not just silence them
That sounds really disruptive. I'm on WIND Mobile in Ontario, Canada with a Galaxy Nexus, and get AMBER Alerts through a standard SMS message. Combined with a Pebble watch, I don't have to worry about disrupting class/a movie when I get them, and I can read the alert without having to take the phone out of my pocket.
Interesting, 4s here in silent mode and it just had a prolonged vibration.
