Just recently Virgin Mobile USA announced a partnership deal with Yahoo, to preload Yahoo’s mobile services to its handsets. Current users with selected phones, will be able to download Yahoo! Mail and Yahoo! Messenger to their handsets, and use the popular services while on the go.
Virgin Mobile USA has around 4.6 millions subscribers. That may not be a big win for Yahoo, but things are rolling, and I guess the search/portal giant is working on similar deals with other carriers and handset manufacturers.
