So I've had an "Apple ID" since the first version of the iTunes store. I've used this ID to purchase items on iTunes, set up Genius Bar appointments, post on Apple Message Boards, etc...This entire time, my Apple ID has been my personal email address "email@example.com". (For those who haven't had enough coffee today, that's not my actual email address). I've also had a me.com account for a few years. I never used the email address "firstname.lastname@example.org" but I've used MobileMe for the rest of it's features. iMessage is now fully functional with my phone number, but trying to get messages to go to my "domainname.com" account does not work. When setting it up on my iPad it asks for my Apple ID and password, which is my "domainname.com" email. When I enter the info in, it says "Unable to verify email because it is already in use." I went to the Apple ID site, to try to change my Apple ID to my me.com account, but when I do that it says "You cannot create an Apple ID using a MobileMe account. If this is your email address, it is also your Apple ID." HUH? Additionally, as a test, I set up iMessage on my father's iPhone. Using his Gmail account, it said the same thing: ""Unable to verify email because it is already in use." When I used his Me.com account, it worked, but now, when he sends me texts, if it comes from his phone it is one chat, and if it comes from his iPad it's a second chat stream. How do I combine it into one? I thought that was the whole point. If anyone can answer these 2 questions, I would be forever grateful.
