The "Facebook Phone" sits up there with Bigfoot and the Loch Ness Monster in mythology and legend, but in reality it's just a term instead of an actual phone branded by the social media service. We've seen the title applied to several phones in the last four years: the HTC Salsa and ChaCha, the Motorola Motokey Social and at least three phones from INQ. Today that term may be attached to yet another device, the HTC First, though we're likely to see a handset with much tighter Facebook integration using a custom Android skin called Facebook Home. We've all heard plenty of rumors about today's event, but now it's finally time to learn exactly what Zuckerberg & Co. have in store for us. Join us for our live coverage of the Facebook event!
