There will not be a version of Firefox for the Blackberry, there is also no Firefox for the iPhone. What is available on the iPhone, and will at some point be available for the Blackberry is the Firefox Home app that allows you to sync your Firefox bookmarks and history with the iPhone and Blackberry. I don't know when the version of Firefox Home will be available on the Blackberry. For details on Firefox Home see http://www.mozilla.com/en-US/mobile/home/
