RIM launched a brand new HTML5 development site to highlight their focus on BlackBerry web development as a platform. The new site is actually very nice and clean which really impressed me. You can check out the new site at:
The other interesting thing is that RIM has integrated Ripple into their dev lifecycle and are really talking about it as a way to build and package your applications from Ripple. Very slick I have to say!They have also released WebWorks v2.2 for both smartphones and tablets. Some nice features in there that you can find in the release notes.
