How do I get my still current phone number off my old iPhone.
I'm trying to sell my old iPhone and I'm trying to make sure all my info is off it. I set it back to its factory settings. But under contacts it still says my number. I want that to not be there since I have a new phone. I have already deleted my old iPhone from my Apple ID list but my old number still shows up
iPhone 4, iOS 7.0.2
