Locked out of icloud
I Have an iPhone 4. When I first got it I set up iCloud. I have not really used it but wish to now. It's registered with an email address that has been deleted and no longer exists and I don't know the old password to allow the delete function in the iCloud section of settings within the phone functions.
Is there anyway of deleting the account so I can set a new one to the phone and start using iCloud. It's like I am completely locked out! Very frustrating.
iPhone 4, iOS 7.1.2
