Facebook app shuts down itself on iPhone 4 I have an iPhone 4. The Facebook application was working fine until this morning. When I start the Facebook app, it shuts down immediately. I tried restarting the phone but it's the same. No jailbreak, no unlock. My phone is 9 months old.
Try uninstalling the app, restarting your phone, and reinstalling it from the App Store. This should resolve the issue.
