How to Download iTunes to an iPhoneby Kara Page ; Updated September 28, 2017
If you purchase a new iPhone from either a licensed Apple store or an AT&T store, it will come with the iTunes application for iPhone--as well as several other apps--already installed. While it is possible to remove the iTunes app icon from your screen, you cannot delete the iTunes software. Thus, recovering access to the iTunes app on your iPhone is simple, because the program is still on your device.
Open your iPhone and tap the "Settings" icon, which is typically located on the first page of apps.
Tap "General," which is the seventh item down on the Settings menu.
Scroll down to the bottom of the General menu and tap "Reset."
Near the bottom, tap "Reset Home Screen Layout," then tap "Okay."
Exit Settings by pressing the menu button on the bottom of your iPhone. The iTunes application icon should now be visible on your screen.
