AutoHello from SBSH Mobile Software is a freeware app that allows you to answer an incoming call simply by picking up the phone and putting it next to your ear. Save that extra tap-swipe! It doesn't use the accelerometer so the battery impact is minimal (it uses the proximity sensor). AutoHello runs in the background, and auto-starts with your phone.
