HTC’s getting the Mobile World Congress hype train rolling. They’ve teased on Facebook that something fast will be unveiled in just five days – the day before Mobile World Congress kicks off.

Who knows, but we’ll be keeping an eye on their Facebook every day leading up to the event to see if they post anything else. Let us know what you guys think in the comments section below.
