The Cupertino, Calif. company has been touting the revenue from its services and app and music stores lately. In the quarter that ended June 30, that division reported revenue of $4 billion, or about 11% of the total.
Apple has also placed restrictions on rivals. In 2012, Apple rejected several iOS apps because they relied on DropBox for storing data and files. To solve the problem, DropBox modified its SDK, or software development kit, so that third-party developers could not steer customers toward a website where they could sign up for the file-sharing service and purchase additional storage.

iCloud is used for storing photographs, email messages, iOS device backups, iWork documents and files generated by a wide range of third-party desktop and mobile apps. The service will be used for password storage — iCloud Keychain — for Apple devices this fall when iOS 7 and OS X Mavericks are released.
The online versions of Pages, Numbers and Keynote — collectively dubbed iWork for iCloud — will also store their documents in iCloud. The online apps are currently in beta, although that program has been expanded in the last few weeks from developers-only to some members of the general public.
As Apple said in its email and repeated on its support site, if a customer has more than 5GB, backup, file storage and mail will stop working until files have been purged or more space purchased.
Apple has posted instructions for customers who want to check the amount of storage they now consume.
