Hi there and welcome Marianne
To clarify, the issue is you cannot purchase an app because you cannot enter in the correct apple id password *****?
Ok, in order to use the phone again you need to get it passed with the password, else the phone becomes unusable. They do this for theft reasons
What happens when you try to sign into the Charter account?
What is the account you registered the Apple with initially?
The only way to get the phone working again is to get this email account functioning. Nothing will automatically roll over, its not possible as there is no way to know from the iPhone that you changed emails, to what ect.
I see bresnan.net does not exist anymore
With who was this email service initially?
ok, but you have to get access to the account to get the iPhone to work again.
What exactly happens now when you try to sign into it here?
