Hi there! Last weekend I went to a mini-jam RIM organized to develop applications to the new blackberry devices.
As Ashley already posted, performance is very good on the browser and blackberry seens to have the tools already in place to allow apps in HTML5 to be converted to their appstore.https://developer.blackberry.com/html5/
Reading the news about WP8 today, I tought, is it possible to create a direct export option in C2 for blackberry devices too? It seens like a cool new market.
