Activation lock on ipod touch
The email account linked to the apple id and icloud that is connected to my ipod i think has been deleted or deactivated (was my mother's email which she says she doesn't have access to anymore). How, if it's possible, do i get back into my ipod? (i remember the apple ID and password but i can't log in to the apple account or icloud with it either, it comes up with the Apple ID is either not valid or not supported)
