A family member today updated the Facebook app on a 3rd generation iPad (retina display) running iOS 5 and now the app crashes every time one tries to launch it. We've tried rebooting the device, deleting and reinstalling the app, and angrily glaring at the machine.
The old version worked. Is there a way to go back to the old version, to make the new version work, or to somehow solve this problem? We'd rather not upgrade to iOS 6 as part of the solution. iCloud backups are off; I don't know if there's some sort of local backup on our computer or not, or what we'd do if that were the case.
