May of 2010, Nokia and Yahoo announced partnership deal that made Yahoo the default search and email provider on Nokia’s phones (and in turn, Nokia’s Ovi will power Yahoo’s mobile and desktop apps).
Nokia OVI chat application will now be completely powered by Yahoo and the alliance will bring newer functionality to Ovi Chat, including the ability to add Yahoo! Messenger friends to your Ovi Chat friend list and access Ovi Chat from a browser.
Excerpts from the email sent by Nokia
To prepare for these changes, you need to begin using the Chat application on your Nokia phone. Access the Chat application from the Chat icon on your Nokia phone or by downloading it from the Ovi Store (see links below). Then, launch Chat on your phone, select Register/Create Account, and follow the instructions to log in with your existing Ovi account credentials.

The Ovi Contacts application will continue to be supported by Nokia, but you can only take advantage of the new Ovi Chat capabilities or chat with other Ovi Chat users if you are using the Chat application. The Chat application also gives you access to other popular IM services so you can chat with your friends across multiple portals/communities from the same place on your phone.
We look forward to seeing you on the new and improved Ovi Chat Powered by Yahoo! service.Sincerely,Ovi by Nokia
