Hate it when your phone rings during a meeting? Lecture? Class? Etc. Same here, I found this neat app about a month ago which has been working well. It accesses your diary info and any appointment marked as busy it silences the ringtone. Neat. Also does by location, but I haven't tried that functionality yet. You just have to check that you leave the app in the background. Search Autosilent in the app store.

Check out this application on the App Store:

I have no affiliation with the app of developer, just a heads up to a useful app.
