I get screen flicker in everything but iphysics. I'm have a 1.1.4 JB with ziphone. It didnt start until after I installed iphysics and iphysics is the only thing that the screen doesnt flicker for. I've turned on compatibility mode and uninstalled iphysics but neither of those fixed the problem. Maybe a fresh restore + JB will fix it? The flicker isn't too bad but it is still noticeable.
