I need to unregistered my iPhone to stop iMessage coming through but my iPhone doesn't come up as registered on my AppleID!?
I have got a new phone (Samsung S4) but whenever I turn my iPhone on my messages from people with iMessage come to here rather than my new phone even though there is no SIM card in here (when I have wifi) this is not a problem at the moment because I can just turn my iPhone of momentarily because I do not use it and this solves the problem, however I want to sell the iPhone and then do not want to next owner to receive all of my messages! I have logged on in order to try and unregister it but it doesn't show up!
iPhone 4
