I've had a similar issue with my Yahoo email account. I got an email from the Blackberry server that the account could no longer be accessed. This happened after the recent infamous network outage.
Cingular couldn't help me so I forked over the $50 to call RIM's tech support. I was told that the BIS server has an issue with Yahoo email accounts at this time. That issue hasn't been resolved as of yesterday.
My work-around was to establish a gmail account to pull my email from Yahoo. Gmail works fine with BIS. I'd suggest doing that in the meantime. But do send the service books again to your BB.
