There is a potential issue with the Cypress, Fullerton, and SCE mobile applications on iOS5. The upgrade to iOS5 causes the launch of the mobile application to shut down as soon as the splash screen comes up.
THE FIX: To resolve this issue, a mobile user will need to remove the application (Cypress, Fullerton, or SCE) from the device and then reinstall it from the app store. This fresh install correctly instantiates the application for iOS5.
Thank you!
