Some applications i have exit after several seconds of using them. Apps such as Customize, AppFlow and even Installer do not work. They will load, and almost immediatley it returns me to the springboard. I have reinstalled both customize and appflow several times. I have even removed them, and then installed them again. Although, i have not taken any action with Installer as im not sure if its even possible to do so. Any help would suffice, as i am left with a long list of unworking apps, many that are important.
