Apple's iPhone is a cellphone with a touch-sensitive display, and it comes with a variety of apps already installed, which a user can disable and hide to prevent their use. You can also disable categories of content so they cannot be downloaded, such as music that contains explicit language, or movies with an "R" rating. You can easily "unhide" apps and content categories on your iPhone with a few taps on the device's display.
Press the "Home" button on your iPhone.

Tap the "Settings" icon on the home screen.
Type the Restrictions passcode at the prompt. A list of apps and content categories appears.
Tap the On/Off option next to the name of an app that you want to unhide, such as the Safari Web browser, YouTube or the FaceTime video-conferencing app, to set it to "on." The app is now enabled, and its icon reappears on the iPhone's home screen.
Tap an item in the Allowed Content section if you want to unhide categories. For example, tap Music and Podcasts, and then tap the Explicit option to set it to "on," or tap Movies, and then tap the name of a rating to enable it. You can also tap Allow All Movies to enable and unhide all movie categories. Now when you browse and search for music in Apple's iTunes Store, you will be able to access material that falls under these categories.
Press the "Home" button to return to the iPhone's home screen. Tap the "iTunes" icon to access Apple's iTunes Store to browse and look for material that falls in the categories you have just unhidden.
