SO, I first noticed this a couple days ago but it became obvious today that something was awry. When someone calls any of my phones in my house (mine, wife's, my work phone) the call rings through to every phone simultaneously. Imagine a facetime call ringing on multiple iPads and an iPhone. This is every cellular call! Two phones on att and one on verizon. Please help! I've had every iPhone since the original and am pretty tech savvy but this one has me stumped. Thanks!
