Android: Yahoo may not be the first app you think of to manage your email, but the company's mobile apps are still pretty sweet. Now, you can sign up for the beta version of the Android app to get the most cutting edge features first. To get the beta version, first you'll need to sign up here, then download the app from the Play Store. On top of the beta, the regular Android app received a couple minor changes. Now you can sync your Yahoo Address Book with your device's contacts and the Mail app has a new People Smart View to see every way you communicate with a person in one place. iOS users also got a couple of new features, including a link preview that turns links into informative cards and a Share button so you can send content via Yahoo Mail from other apps.
