Silence your BlackBerry by flipping it over
An app that can be argued as a feature that should be baked into the BlackBerry 10 operating system, Flip Shush allows you to mute and pause media and phones can simply by flipping your BlackBerry over, face down. Being able to mute media is pretty cool, as it works for all media, including when watching videos in the browser.
When it comes to muting phone calls and notifications, you're going to have to make an in-app purchase but I can see this being a wanted feature as you don't have to put your BlackBerry on silent when going into meetings you can simply turn your device face down on the table and all calls and notifications will be silent. Great for those who forget to silence their phone during meetings. On top of that it means you can't see the flashing LED, so you can be sure that you are giving your full attention to whatever is at hand.
