Changed Apple ID & iCloud ID But Can't Change It On The Phone
A while back, I changed my Apple ID and iCloud ID to my new email address instead of one that I deleted a while back.
On the phone, iCloud is still configured with my old ID/address. I tried turning off iCloud on the phone so I could just set it up as new, but I can't. It tells me I need to disable Find My iPhone, but the only way to do that is to verify my ID and password, which it won't accept since the ID isn't valid anymore.
