Problem erasing an iPad with old Apple ID.
I want to restore my iPad 3 to factory settings to trade it in. The "erase ..." function does not work because the iPad was originally set up using an Apple ID using Verizon email. (MyUserName@verIzon.net) I switched from Verizon to Comcast and my Apple ID now uses Comcast email as part of the ID. (MyUserName@comcast.net). When I go to "erase ...", I am asked for my password which does not work as I no longer have a a Verizon internet account or email. I can restore using my Comcast Apple ID, but the Verizon information comes back. Apple support has not been helpful. Thanks.
