Since I downloaded the iPhone software update on Wednesday, my app store apps have simply not been loading. I click on one, it launched, and within one second it crashes and collapses back. Things I've tried so far -- - Uninstalling and reinstalling all apps. - Uninstalling apps, rebooting phone, reinstalling all apps. - Buying a new app and installing it, only to find that it, like all the other apps, crashes and refuses to launch.
