Following an avalanche of stories breaking right now, like this one from ARS Technica

Users have discovered a bug in Apple's FaceTime video-calling application that allows you to hear audio from a person you're calling before they accept the call

I only FaceTime with family, I guess we’re gonna find out how many people actually use FaceTime! My guess? Pretty few use it outside immediate family.

Now does that mean that this bug doesn’t apply to me? Not at all, anyone can FaceTime my phone, and now they can listen in, even if I don’t pickup on my end. Software is hard, it will come down to how quickly Apple acts on this one.
