Assuming this app goes to Cydia, which I doubt, it is not worth jailbreaking for. Trust me. It's really clunky.... and I would never use it as my everyday browser. Ugh. No forward button or way to move forward, for instance. If you accidentally go back a page there is no way to simply go forward again. And the facebook feature to me is stupid... I would rather the time spent on that had been spent on making the app itself better. Crashed on me when I tried to go to history too... which I was doing because there was no forward button. Finally, I have yet to get it to work with any the flash videos I have tried.
I can't imagine all the issues I have had have to do with their servers. I didn't even get to that point, aside from videos they show in a search box--and I will say that those did in fact play. But even during playback things were kind of odd: the usual video maximize button was there but didn't work.... tapping it once made it go away for good. Maybe these are first release issues but so far I can only see this being useful if this app played the Flash videos you simply had to have on your iPhone/iPad.
