When your phone rings in some unfortunate situation, you want to silence the ringer as soon as humanly possible. Problem is, it's usually tough to reach - it'll take a few more rings to get it out of your pocket, or backpack, or whatever, and press that little button. Thankfully, an Android app called Shake2MuteCall aims to make it a little easier: just smack or shake your phone, and it'll shut up. It uses the phone's accelerometer to detect intentional motion while ringing - and lets the user set the sensitivity, which is sure to prevent frustration. It seems similar to - but even better than - the HTC HD2's ability to silence when the phone is physically picked up. Things just keep getting better, huh?
