BlackBerry has something fun going on at Mobile World Congress this year with a event called App Circus. In a nutshell, App Circus is put on for local developers to showcase their app to a panel of judges for a chance to win a PlayBook (first prize), with all other contestants getting a free BlackBerry Torch for participating. Each contestant was given 3 minutes to showcase and present their app to the panel of judges. Some very interesting ideas and apps were presented and we don't want to spoil the end result for you, so check it out and leave us a comment on who you think should have won the App Circus event.
