The app is not working very well on my blackberry curve 8310. It takes forever to load the app and even after I select my car and input the data it takes 1-2 minutes to update. Also the screen is rather plain now and does not look anything like the above screen shots for iphone or android.
No, it does not work. When I head to m.fuelly.com, the blackberry browser window goes white and a page appears to be loading, indicated by a status bar at the bottom of the screen. After the "Loading Data..." status is complete at 185k, the browser window appears completely white without any icons/text/buttons. The page title (Fuelly Mobile) is listed at the top of the screen, but there's nothing to click on or fields to enter.
Let me know if there are more details I can provide.
