I have the same problem. Thanks for the cust svc number post. I initally called SBC but the number but after 20 min they said yahoo is the only people that can help - and they gave me a number to call - disconnected. I found this post and they were helpful - said that the form is looking for an sbcglobal.net domain for the ID. Since I am a Prodigy customer (bought by Pac Bell, bought by SBC, yada), prodigy tier 2 tech support can help. He transferred me and THAT number is disconnected. So I am back on hold here.

Anyone else have that explanation for the "invalid password" issue?
