Apps no longer working

[mel3476]

I updated my iPhone 4 with iOS 4.3.3 last night and ever since, none of my apps open. When I select an app, the screen goes black for about a half a second, then goes right back to the window I was on. I have no idea why this is going on or how to fix it. Do I need to roll back the version of iOS software? If so, how do I go about doing it? Any help would be greatly appreciated...thanks!

i think you should downgrade first and see if the problem is still there.
here you can see how to downgrade:

I have had this happen to me before. Before you go through the downgrading process, just go to the appstore on the iPhone and download any random app. For some reason, installing a new app fixes all the others and they open correctly. Hope this works for you!

This did work. I had a couple of app updates that I downloaded and installed and it enabled all of my other apps to work. I have no idea how or why it worked, but it did. Thank you everyone for your help!

This may be caused by data lose of iTunes account authorization when updating. iOS will check authorization info of apps when running them, if no authorization info found, it would close the app. So when you install an new app with your account, the authorization info will be saved to your updated device, so it won't happen again.
