Reinstalling and restoring iPhone apps

Don’t panic if you’re having issues with an application. It’s very easy to restore any of your third party apps to their initial state, which will usually fix any problems you might be having. Please note that reinstalling an app will typically delete its settings. Also, only third party apps can be deleted. The apps that come with your iPhone can not be removed.

In most cases one of the following will help.

1. Restart your iPhone

2. Reinstalling an iPhone app

3. Restoring an iPhone app to its default settings

4. Help from Apple
