"Yahoo! appears to be upgrading their servers to a new version of their software. This new version requires a new authentication method. The latest version of Pidgin, 2.5.6, does not support this new authentication method. The next version, 2.6.0, will, but it has not yet been released. Version 2.5.7 does. To continue using Yahoo! IM, upgrade to this version. See the Pidgin web-site for details."

We have the 2.5.1 version which it won't work anymore on Yahoo IM upgraded servers.

I tried their solution, using that list of IPs but with no luck..
So Is this like the end of pidgin on maemo?
