Virgin Mobile USA, considered to be the first MVNO in America, has landed Yahoo! as of last week to get the web portal's mobile services available to its 4.6 million wireless customers. Yahoo! Mail and Yahoo! Messenger will be first up to bat, with those mobile services coming as downloadable applications for several Virgin Mobile handsets this month. In addition, Virgin Mobile will be pre-loading Yahoo! Mobile applications on many of its phones starting now, according to both companies.
