I know a sneaky but functional method that works. I just got my tour today, and when I used the BBDM's device switch method to move all my Curve's apps. This included the amazon app which came over. It works perfectly too.
I'm not the best bb techie. but I bet there are other ways to do so.
There is an Amazon link. But better yet, skweezer precompresses the website so the pages load faster and in mobile view as well. There are a lot of links on the skweezer site. Check it out, especially the "Top" menu link at the top of the page.
