Take a crack at this. I had to restore my phone and set it up as a new phone yesterday. Some of my wife's apps are under my Apple ID since she bought some stuff from my account before she set up her own. She now has her own Apple ID that is associated with her phone. This morning I got a popup on my phone that said something to the effect of iMessage and FaceTime for my wife would be using MY phone number. The only option was to hit OK. I thought it was odd but shrugged it off, there wasn't anything I could do. Later on I sent my wife a couple iMessages which worked fine. However I also sent my friend an iMessage; he received it. However, so did my wife? What's going on and how can I fix this? Definitely don't want messages going to the wrong recipient, or in this case, multiple recipients when they shouldn't. Thanks.
