iCloud stores your photos, apps, contacts, calendars, and more, and wirelessly pushes it to your iOS devices and computers, automatically keeping everything up to date.
iCloud features include:
With iCloud, you get a free email account and 5 GB of storage for your mail, documents, and backup. Your purchased music, apps, TV shows, and books, as well as your Photo Stream, don’t count against your free space.
