Do you want to play a game? Apparently Motorola does, as the company has invited its Facebook fans to play "Guess the Smartphone." Motorola posted an image of a black rectangle with a big red question mark on its Facebook page, explaining that it'll give a clue to the smartphone's identity each day this week, with a "big reveal" planned for Friday. The first clue is that this mystery smartphone features 4G LTE connectivity.

Considering how frequently we've seen the Motorola DROID RAZR HD and its 720p display leak in recent months, that's the first device that springs to mind when thinking about what Moto might be teasing. Of course, the company doesn't say that this is a game of "Guess the New Smartphone" or anything like that, so it's entirely possible that the phone under that black rectangle is one that's already been announced. Guess we'll just have keep an eye on Motorola's Facebook page and see what other clues are shared. We'll keep you posted as we learn more, and until then you can share your thoughts on which phone Moto is alluding to in the comments below.

UPDATE: As suspected, the product that Motorola is teasing on its Facebook page isn't a new phone. Chloe Albanesius, Managing Editor for News at PCMag, has been told by a Motorola representative that the company is simply getting involved with its Facebook fans and talking about its current device lineup.
