iMessage on iPod Touch
I recently updated my son's iPod Touch to the latest software and now he has access to iMessage. The problem I have is the iPod is registered under my Apple ID and therefore when I go in to set up iMessage it wants to use my email address. If I try to delete that address and put in his email address, it prompts me to change the email adress associated with my Apple ID, which I don't want to do. How do I send iMessages from my iPhone 4S to his iPod Touch? Does he need his own Apple ID and therefore his own iTunes account?
