For Seniors: Enable Auto Downloads of Purchases from Other Devices
You can enable auto downloads of purchases from other devices on your iPhone 4S. With iCloud, you can make a purchase or download free content on any of your Apple devices, and iCloud automatically shares those purchases with all your Apple devices.
To enable this auto download feature on iPhone, start by tapping Settings on the Home screen.
To use iCloud, first set up an iCloud account.
In the options that appear, tap the On/Off button for any category of purchases you want to auto download to your iPhone from other Apple devices: Music, Apps, or Books.
At this point, Apple doesn’t offer an option of auto downloading video content using these settings. You can always download video directly to your iPhone through the iTunes app or sync to your computer using iTunes to get the content.
