how to backup from icloud
how do I restore to a new IPhone 5 from a 3gs Icloud backup?
iPhone 5, iOS 6.1.4
Is the 3GS iCloud backup under the same Apple ID?

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.
