Just over a week after its announcement, Facebook Home is now available to download on Google Play. Facebook's Android launcher is currently only available to US users and is supported by only a select number of devices, including the HTC One X, HTC One X+, Samsung Galaxy S III, and Samsung Galaxy Note II for now, with the HTC One and Galaxy S4 slated to receive support in the future.

Home is a family of Facebook apps that overhauls your entire device, turning it into a Facebook phone. An app called Cover Feed overhauls the homescreen and the lockscreen, giving you updates on what your friends are doing without you having to launch an app, or even unlock your phone. You'll also see a round icon with the face of whoever you're talking to, called Chat Heads. The chat feature works with SMS and Facebook messaging, popping up new alerts on top of the app you are currently viewing. Earlier, Facebook updated its Android Messenger app to include Chat Heads, opening the feature to those that don't wish to install Home.

AT&T has also opened orders for the HTC First, which comes with Facebook's new Home launcher out of the box — priced at $99.99 on a two-year contract. Head on over to our HTC First review for more on what you can expect from the phone that is "about people, not apps."

Update: The Facebook Home rollout isn't going very smoothly — some users are unable to load the Google Play link and download the app, but we have successfully downloaded Home and can load the page at this time.
