At some point, everyone's been burned by their iPhone going off in the worst possible place. When you see there's no option to decline the call, it's a mad scramble to press every side button or sling the phone through a wall at the speed of sound. But you've seen the on-screen option to decline calls before, so what gives? Fair warning: it's a really simple, forehead-slapping answer. When your iPhone is locked, incoming calls display the "slide to answer" control. When your iPhone is unlocked, you get the option to answer or decline the call.
