HTC is tipped to be working with Facebook on two Android smartphones bearing the social network’s official branding. According to CityAM‘s unspecified sources, the two handsets will use Facebook’s color scheme and support Facebook Voice calls and IM, as well as putting the social network’s news feed and messages on the homescreen.

Neither company has commented on the rumors, which suggest the new phones will debut at MWC 2011 next month, but SlashGear has heard independently that at least one of the devices should have a physical QWERTY keyboard and Facebook CTO Bret Taylor has recently insisted that the company’s primary focus for 2011 is mobile. Android Community will be at Mobile World Congress to bring back all the details of any announcement.
