So, I have my Locale set to turn everything silent when I'm on campus. I even let it use GPS so it gets things right. But I'm in class today, and an email notification goes off ("DROIIDDD")--I look at the phone, and Locale has apparently set me back to default; must have lost its fix on my location. So then I manually set the phone to silent... and five minutes later, BAM, it rings. Locale had reset to default again, which preempted the silent mode. I guess the solution here is to set Locale's default to silent, but then obviously it'd be putting itself on silent all the time... I wish the default mode could just detect the last user-defined settings. I love this app, but I'm thinking that it's got a long way to go before it's actually, you know, useful.
