Can i erase my old iphone and deactivate find my iphone if I have already switched my service to my new phone
I have purchased a new iphone and switched my service.
I didn't erase my old iphone or disable find my iphone before I made the switch.
I'm trying to figure out how to erase my phone and disable find my iphone service now so I can sell my old device.
iPhone 4S, iOS 7.1.1
