iPhone 3rd Party Apps Not Loading?

Are your 3rd party apps not loading on your iPhone?  To fix, try downloading any free app through the App Store.  The reason your apps are not loading could be because your iPhone lost your iTunes password.  As such, when you download an app, it asks for your iTunes password — then the password will be saved again. 

So once you have your password re-saved, try to pull up other apps.  It should now work.
