It turns out that this was a public demonstration of BBM running on iOS and Android and while no videos were allowed to be recorded, those who tried the app out claim that it is a pretty smooth experience. The UI for iOS and Android is said to not differ too greatly from the original app running on a BlackBerry smartphone, so for those who have transitioned from BlackBerry to iOS or Android, this should not be too foreign a concept for you guys.
The app is said to be on demo this week and is available for you to try out at the BlackBerry Experience building, so for those living in Toronto, you can hit it up and check it out for yourselves!
