Mysterious swiveling Acer phone sighted

It’s Just a couple weeks before the 2009 Mobile World Congress kicks off in Barcelona. Thus, a flurry of leaked mobile devices continues to grow, day by day.

In today’s pre-release news, BGR has got his hands on a crystal clear image of an unidentified Acer smartphone.  All that can be gathered from the shot is that it has a strange swiveling QWERTY key pad. Is it just me, or is it really unclear how the two halves will slide back together?

Oh, and it has a touch screen (duh) and it’s not clear whether it will run on WinMo, Android, or some other funky fresh OS.  Keep your eyes peeled, kids!
