How do I delete an app and re-download?

• To delete the application from your device, press down on the icon until all your icons start shaking. An X should appear on the top corner of the icon. Press the X, and you will be prompted to delete.
• Go to the App Store, search for the app, then re-download the application with the same iTunes login, and you will not have to purchase it again. See: http://support.apple.com/kb/HT2519.
• Please restart your device after re-downloading. See “How do I restart my device?”
