It looks like Facebook is putting its purchase of group messaging app Beluga to good use, as it just announced Messenger, a mobile app for Android and iOS that acts as a sort of extension to Chat. In addition to the aforementioned group chat ability, Messenger's goal is also to simplify all your conversations, whether it be through Chat, Messages, email, or text. Photo and location sharing options are also available.
Messenger is not yet available, but should be launching today, so we'll make sure to let you know as soon as it hits the Android Market. The app is now live in the Market, hit the widget below to grab it. Now, lets hope Facebook has the time to put some thought into its regular Android app.
