Mobile World Congress 2011 is over, and the gang's back together once again, but before we say adios to MWC, we thought it'd be good to recap some of the highs and lows of the show. Plus, Nokia may have signed on with Microsoft and Windows Phone 7, but the Finnish handset manufacturer says it's still committed to Symbian. We discuss their future, as well as RIM's, and much more (hologram phones!) on this week's episode of Dialed In.
