Hi - so we both have iPhone 4S and since latest upgrade my husband has been receiving text sent to me personally. This only happens if he also has the sender's number in phone book. So far, no embarrassment yet! Please help. Many thanks
iOS 6 merges phone numbers with Apple IDs, and this causes confuzzlement with anybody who shares an Apple ID, because iMessages and FaceTimes sent to their number will also be sent to any device also registered with that Apple ID.
As far as I know, the only option is to get different Apple IDs for signing into iMessage and/or FaceTime. Settings -> Messages -> Send & Receive. Sign out of that Apple ID and sign in with different one. If you use FaceTime, use the different ID there as well.
