Having been in a meeting today where yet another phone rang, I was very happy to see this app for the Android. STFU - that is Shut the Phone Up - makes it easy to silence that cell phone. Just turn your phone upside down and it is immediately set for either silent or vibrate (your choice). STFU is just 99¢ and worth every penny. You pay a little more for the cute name. RD Mute is a similar tool available for free. Now I've taken care of my phone, what about the guy next to me?
