Still using Yahoo! Mail, eh? Good news! The app just hit v2, which, like most full-version releases, brings all sorts of new goodies. First, and probably the most noticeable, is that the app is now called Y! Mail and it has a brand spankin' new UI. Don't tell GMail I said this, but I actually think Y! Mail's new look is pretty decent.
Aside from the pretty new interface, version 2 also brings increased stability, more reliable push notifications, better battery performance, and better security, as it now has SSL activated by default.
Good stuff for those who are still attached to Yahoo!
