Blackberry Apps

Does anyone make their own apps with the Plazmic (free) software that Blackberry provides?

I just got me a new Nextel Blackberry Curve and have been playing around with it. I see there is a lot of apps for sale out there. I know everyone is trying to find ways of making money. Was thinking that making your own apps might be a good opportunity.

You can make background images and small animations. I don’t know if Blender can be used to make stuff and then import to Blackberry.

Just wondering if anybody has any info on this?
