My wife and I have the latest 5.0 beta 4. I can send imessage's to others on 5.0 but when I set up my wife with her own me address in icluod when I turn on her message and activate it, it gives me an error message that states " check your network connection and try again." this happens if I'm on wifi or 3G. It also gives me this error message when I try and activate her FaceTime as well.
