Back when I had at&t DSL, I made the mistake (?) of associating my yahoo account with my at&t account. This turned out to be problematic, as once I cancelled the service, the at&t branding remained.
Just recently did I figure out how to remove it:
Complete the following steps to disconnect your Free AT&T Email and Portal account.
Note: A Free AT&T Email and Portal account provides access only to the AT&T Email and Portal (http://att.net). Your Internet access is provided by a company other than AT&T and will not be disconnected.
- Go to http://att.com/internetaccount and login
- Click Profile Management
- Enter password and click OK
- If the Member Management screen displays, select your Member ID
- Scroll down to bottom of the page and select disconnect my portal service
- Click Yes
