The questions lead me to believe that Blackberry is hanging their hopes on a native wrapper around an HTML5 framework/interface like Phonegap, which is such a horrible mistake, IMO. Platforms should push for the best experience for users and let 3rd parties like Phonegap deal with the 2nd-class user experiences while bringing more developers in.
Frankly, I don't think a platform wants developers who prefer quick-and-dirty frameworks like this. Take some pride in your platform!
