OK so I sold my 4s to my Aunt for giving me her early iPhone upgrade. She gave it to my cousin and just got the phone today. I did a complete reset and sent the phone off to her. I just got a message on my iMac and ipad saying my cousins iPHone is now using my email address for Facetime and iMessage . HOW DO I GET THIS REMOVED?! It so odd if she sees my conversations. anybody please help?
