i got that message as well recently when i tried installing facebook on my work issued 9700 from app world. instead i just installed it from the blackberry home page on the browser, it worked fine. i think it might be the new release for app world that is causing the issues. on my personal bb 9000 i still have 1.1.0.24 and on my work bb 9700 i upgraded to 1.1.0.33 this seems to be the one causing issues. i remember reading somewhere, may have been here, that other users were having issues with .33 as well, which is why i was hesitant to upgrade on my personal berry.
