iMessage

You have to set up Messages on all your devices and sign in using your Apple ID

 

You have to add your apple ID to iMessage on your iphone to receive messages on both devices.

Basically, for now, messages going to your phone # go to your phone, messages that go to your Apple ID go to any device which has iMessage setup with your Apple ID.

In iOS 6, it will be unified so even messages going to your # will go to all your devices.

 

In the mean time though, if you add your Apple ID to iMessage (in settings) and people message you through your Apple ID instead of your #, you'll get it on both your phone and computer.

 

Ahhh what a pain... I was so excited for iMessages to work on my new computer. Oh well... iOS 6 I wait.

 

If you just have everybody iMessage you to your Apple ID, it will work fine. That's what I do.

 

I'm not going to do that though. The idea of iMessage is convenience. I know it might sound like I'm being stubborn about this, but It's like trying converting a friend to use a different email then the one you have been using for the past couple years. It's a head ache because they have to remember. Then they don't and you are annoyed.

Just doesn't seem worth it, but when iOS 6 rolls around it'll be really nice.
