Mark Zuckerberg

We're starting to fill our schedules for Mobile World Congress next month in Barcelona. And one must-see keynote address will come from none other than Facebook founder and CEO Mark Zuckerberg, who was just announced as a speaker this morning.

Mobile World Congress

We're not expecting any new device announcements, especially given the failure of last year's HTC First/Facebook Home experiment, though stranger things have happened. No, instead what we're likely to hear is a sort of "state of mobile" speech that's more common at MWC. Google's Eric Schmidt has done so in past years, and it usually proves to be interesting.

So set your clocks for 4 p.m. Barcelona time on Feb. 24 — that's noon on the east coast of the U.S. And as always, we'll be there live to bring it straight from our eyeballs to yours.
