messages
If I send someone a message through iMessage from my Macbook and they are to receive it on their iPad/iPhone, what will happen if that person has changed their mobile phone number since I added them as a contact?
Will they still get the message?
I initially contacted this person with an email address.
Go to settings on the iPhone. Go to the 'Messages' settings. And select Receive At.
See what it says there. It should be your phone number not Apple ID or email.
If you have a Apple email listed. You can remove it by.
Clicking the 'Apple ID youremail@me.com'
You will get a popup which lets sign out thus removing the mac email address.
If it is not an e-mail address registered for the service, it will turn red.
Additionally, you will get an error message when trying to send the message.

Usually iMessage is tied to the email associated with iCloud. If the person is using iMessage on their new number they would have logged in with their email address and hence receive the message.
