The young billionaire had a recorded message for HTC's Mobile World Congress event today, praising HTC's new social efforts. He also announced that there will be more "phones with a deeper social integration" coming in 2011, with "multiple devices" due and possibly even as many as a dozen. Quite a change in position from "Facebook is not building a phone" eh?

Although, technically, that is just about correct—everyone else will be doing the phone-building on Facebook's behalf.
