I see that you've tried to access your account by "everything, put in phone #, type in e-mail name". Did you try this through the Yahoo! recover password *****?
I'm trying to assist you with you password ***** with some questions and troubleshooting. I just need to clarify the steps you've already taken.
The Yahoo recovery form will need all of the information that you entered when the account was created so make sure that if you use an old phone number or alternate e-mail address when you created the account.
Did you create the account through the Yahoo! site or did you sign up with AT&T and they created the Yahoo account for you?
