Delete an app.
To delete an app you downloaded from the App Store, touch and hold its icon on the Home screen until it starts to jiggle. Tap to delete.\n
If you delete or drag all apps out of a folder, the folder is automatically deleted too. When finished, press the Home button.\n
Note: Deleting an app also deletes all of its data. You can redownload any app you’ve purchased from the App Store, free of charge. You can’t delete built-in apps.
