You know that weird quirk of physics where toast and iPhones always fall face down? Well, I have good news: Your next iPhone might have the ability to change its angle mid-fall, so that it lands on its side or back, saving the brittle glass display. Apple is researching a whole host of weird and wonderful ways of correcting the trajectory of a free falling smartphone -- such as using the phone's vibration motor to change the fall angle slightly, or mall canisters of compressed gas to act as retro thrusters that can slow the descent.
