There might be other issues because the original error was"this app is for Sprint customers only" or something along those lines. All I did was change the banner, reboot and the app worked. I didnt have to reinstall the app or anything.

Try going into the appllication under menu/settings/applications/manage applications/All

Find the app and clear the cache

Other than that a format wipe might help, then again Im not sure.
