Yahoo! Go for Mobile has been available for S60 devices since the beginning of the year and just yesterday Yahoo announced it for Windows Mobile Smartphones and Pocket PC Phone Edition devices. You can download the free Yahoo! Go for Mobile application and then see that you have the integrated suite of Yahoo! Mail, Search, News, Contacts, and Photos. Yahoo Messenger is not supported on the Windows Mobile client. I used to be a heavy Yahoo! user, but have since moved on to Gmail and Google for most things. This mobile client though is very well designed and may help bring some people back to using Yahoo for more features. This new client works on devices like the Treo 700w and Motorola Q.
