Here’s a neat utility for Windows Mobile. It lets you set your phone to mute for a set period of time and then restores the volume automatically. So if you’re on a subway and don’t want the game you’re playing out loud or at a movie or taking a shit…wherever you are that you prefer people to not hear your phone and you’re afraid you may forget to restore your volume.
You can check it out here at XDA. This is a free app but of course, if you like it buy the dev a beer. Thanks for the tip Jimski
