Stolen iPhone, change Apple ID Confirmation code on stolen device? Need Help!
My moms iPhone was stolen a few weeks back, I got it replaced and bricked (activation locked) the iPhone, now my sister is using the new replacement phone, with her own Apple ID (Mom passed away a few months ago) apparently my Moms Apple ID is still active on the old stolen iPhone, add to that some family knows the Apple ID password I think it got out since I’m getting charged for iTunes purchased from that device. I’m about to change the Apple ID password but I’m worried the confirmation number will pop up on the stolen iPhone? How should I proceed?
