So I sold my iphone 4S this week, yesterday I got the notification that my email@example.com was now able to send and receive iMessages and facetime calls, I ignored it. This morning I got the same message but accepted it this time and it told me that all my associated apple id/emails were able to send and receive imessages and facetime calls on the other person's iphone(the one I sold). I've already talked to the person that I sold it to and they said they aren't receiving any of my iMessages, I've disassociated the old iphone off of my apple services. Is there anything else that I need/can do to make sure that my iMessages wont be sent to the other persons phone? Thanks in advance.
