This week at Mobile World Congress we had the opportunity to talk with Alan Panezic, VP of Enterprise at RIM about what the company is doing to keep existing business customers (and possibly even lure new CIOs) in the warm and secure embrace of its enterprise services while still giving users personal freedom to fully enjoy their devices. RIM's secret weapon? BlackBerry Balance on the PlayBook running OS 2.0 (of course) and BlackBerry Mobile Fusion on the server side. Take look at our video and remember -- that corporate PlayBook of yours may still lack BBM integration but IT professionals are people too, so be gentle with them!
