iCloud stores your music, photos, apps, contacts, calendars, and more, and wirelessly pushes them to your iOS devices and your computers. iCloud is integrated with your apps, so everything happens automatically.

For example, if you buy a song in iTunes on a Mac or Windows computer, it appears on your iPod touch and iPad. When you snap a photo on your iPhone it’s automatically sent to your iPad. You can start creating a Pages document on your iPhone, and put the finishing touches on it from your iPad. There’s no need to dock your iOS device or sync it to your computer. 

Before you can use iCloud on each of your devices, you need to sign in to iCloud using your existing Apple ID or a new one, then turn on the iCloud features you want to use.

You may have set up iCloud on your iOS device or Mac when you first used it. To make sure it’s set up correctly, or to set up your iCloud account on another iOS device, computer, or Apple TV, go to the set up iCloud website listed below.

After you set up your devices, iCloud begins to push information to each device. You can also now sign in to iCloud.com and start using the iCloud web apps.
