Can't restore my iPhone 4
Hello! MY mother just give me her iPhone 4. I want to reset end erase all the data from the device, but my mother make a little mistake: When she creates her iCloud account, she write wrong her e-mail... The device know that its not a verrified e-mail, but because of that i can't restore this iPhone... How can I change the account or reset the device without needing the password confirmation of a wrong ID?
Thank you!
iPhone 4, iOS 7.1.2
