When you go through Setup Assistant on a new device using iOS 5 or later, choose "Restore from iCloud Backup" and enter your iCloud account and password. You will see the three most recent backups for each of the devices on which you enabled Backup. Choose which backup to restore from.

After your device restarts, your settings and accounts are restored and Backup starts downloading your purchased music, movies, TV shows, apps, books, Camera Roll, and other content.
Note: You may be prompted to enter the passwords for all accounts enabled on your device. You may also be prompted to enter the password for for any iTunes, iBookstore and App Store accounts for which iCloud Backup is attempting to restore content.

A progress bar will appear underneath the apps that are being downloaded. To prioritize the restore of a specific app, tap its icon. Restore will attempt to download the same version of the app that you had installed previously. If that version is no longer available, the latest version of the app will be restored.

If you are using iTunes Match (U.S. only), you can download any of your songs, albums, or playlist from iCloud after the restore is complete.

To check if the restore is complete, go to Settings > iCloud > Storage & Backup.
