This app isn’t exactly going to light the world on fire, but it’s practically a must if you’re a Yahoo! Mail user and an Android Phone owner. The Yahoo! Mail app is a clean mobile version of the popular email service. It’s fully integrated with Yahoo! Messenger, and you can use the app to sign into multiple accounts, if need be. You have the standard array of mobile email features – push notifications, search, and attachment support – at your disposal as well. Rich text formatting is also fully supported, and you can preview photos from your inbox, which are a couple of nice added extras. It’s available now for free from the Android Market, and it works well, so if you’re one of the Yahoo! Mail faithful, you might as well give it a download.
