Facebook Home begins international rollout with Canada and the UK

The first regions seeing the app's release are Canada and the UK, which makes sense, because those are the regions that tend to get the Facebook goodies first, like the iOS voice calling feature. Home still has the same limitations as far as device compatibility, so even if you live in Canada or the UK, you'll still have to have either a Samsung Galaxy Note II, Galaxy S III, HTC One X+, One X, or One to use the app. 

Eventually, UK users will also have the option of buying the HTC First, which has Home baked-in. Both EE and Orange have confirmed that they will carry the phone. As yet, no carriers in Canada have announced availability of the First.
