I often forget to revert back silent mode whenever I enable it, especially during meetings or movies. This is simple app that takes a timeout value, after which the phone will automatically come out of silent mode. Optionally, it will also sends an SMS to the missed callers with time at which your phone will come out of silent mode. It can also be restricted to sent SMS only to users in your Address Book. If the user you are calling also has this app installed and has enabled SMS on missed call, you will get an automatic notification when the users phone comes out of silent mode. The notifications can be clicked to directly dial the number without going back to address book.
