We are getting a new Native SDK today but RIM has been kind enough to detail what new features are coming today. There are some whoppers in here including my favorite which is Cards. It allows deep integration between apps to call up functionality from another app within your app. Developers can also create their own cards beyond RIM’s so this is truly extensible. In other words you can have a file manager that pulls up a card for a picture editor or video viewer. You can slide in the card like Cascades and it looks beautiful.
RIM is also adding the BBM social Platform, Email, Calendar, Contacts, Advertising, Push, and many more features. Check out all the explanation on the BlackBerry DevBlog.
