i thought sky fire stopped their development on an app for blackberry long time ago. who knows if they got over it and started the production again. i just don't see sky fire being made available for blackberry very soon.
The last beta version was released back in August I think. I cannot remember exactly. On the private beta board for skyfire, the last response from them was around the first of the year saying that they had no news to share on the progress and that the program, for lack of better words, had been halted. The app definitely had some potential, streaming video with in the browser was definitely one of them. However, there was a lot of bugs and usability and speed were very poor... And as of now, I think they have shut down or dramatically restricted their BB servers because I cannot get any of the beta versions to conenct.
Unless there are some dramatic changes when the next version comes out/if it comes out, I wouldn't keep your hopes up. At this point, all three functioning browsers work much better, those being the native browser, opera 5 beta 2 and bolt 1.7.
