Don’t laugh. I know the Facebook Phone has been rumored for ages. Mark Zuckerberg himself shot down the idea, saying in July that building his own phone doesn’t “make much sense” for the company. However, that wouldn’t prevent someone like HTC from building a Facebook phone, reportedly on tap for mid-2013. Even if an actual piece of hardware doesn’t materialize, Facebook can’t afford to be a mere sharing button on iOS and Android. More than 543 million users access the service from mobile devices, and the network is under enormous pressure to monetize this activity. Now that Facebook has sped up its sluggish app it will likely become much more of a platform within a platform on iOS, stealing precious mobile ad revenue.
