Does anyone know how to unify iMessage on ML, because as of now it is a mess. If I have a conversation with someone via Mountain Lion, it will open up as a separate contact and conversation on the phone. To make things worse, if we are conversing via laptop, the phones will be alerting constantly. Surely the application should know what device is being used. I suspect that cannot be fixed though. However, surely there must be a way to unify the conversations. For the contacts I am talking to, in there contact settings I have stored their emails so that is not the problem. Also, for my message settings I have set it to "receive at 2 addresses" which is what it should be. But still, it runs two separate conversations. I'm running the latest version of iOS 5 on my iPhone.
