Facebook Home is here, and although it's not tied to its flagship hardware, the list of phones that officially support it is kind of underwhelming. If the phone you have isn't listed, have no fear: you can try out Facebook Home too, and the workaround is pretty easy.
The process is almost identical to installing the APK that leaked before Facebook Home came out. There's just a few things you have to do. First, you've got to enable app installation from unknown sources in security settings. Then you've got to delete all the Facebook apps you already have. Depending on your ROM, that might require root. From there all you have to do is download and install the three APKs modified by Modaco's Paul O'Brien, sign in, enable Home and bam, you're done.
Unlike the leaked version, this modified one mostly works on most devices out there. The one thing missing is chathead integration, which for the moment is borked. Lucky for you, chatheads are in the stock Facebook Messenger app if you want to check them out that way, but you can't have your bootleg version of Home installed and do that, so take your pick.
In the future, Home should be coming to more phones; there's no reason it couldn't run on hardware like the Nexus 4 for instance. But it'll probably never work on your ancient, shitty one. While you wait to see if your phone gets an official version, this is a way to take a first-hand peek.
