The best part about this is that you can basically shut your phone down during the hours you know you'll be asleep, but don't have to worry about restoring the settings when you wake up. Even if you have an alarm set on your phone, just program SweetDreams to "wake" your phone before the alarm is set to wake you. A restful night's sleep and battery savings? Sign me up! The free app is available in the Android Market by searching for "SweetDreams."
