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.

  • BTW it's the last version of Facebook: 4.1 and iOS 5.1

  • The iPhone 4S is less than 9 months old. Do you have an iPhone 4?

Try uninstalling the app, restarting your phone, and reinstalling it from the App Store. This should resolve the issue.

  • I just reinstalled the app and it worked, no need to restart the phone. Any clue about why did this happen?

    It was probably a corrupt plist. Since the OS is closed, you can't remove just the plist and restart the app. You have to remove the whole app and reinstall. A little cumbersome, but effective.

  • Same thing worked when I had (numerous) issues with the NYTimes app.
