Did anyone get a solution to this problem?  I've been trying to get my email auto-fill back for the past week.  An on-line chat agent told me to call Yahoo at 866-562-7219.  I called.  The message says there is no phone agent support but to send an email with my problem.  I did that and I'm now told it will be 24 hours before I get a response.  It seems to me that if At&T knew there was a problem they would let their agents and customer know about it. 

Did anyone ever find out how to report a problem?
