While it has issued its final reminder for its customers to download their documents from the soon-to-be-defunct iWork.com, Apple has today updated its suite of iWork apps for iOS.

The simultaneous updates to the iOS version of iWork, which comprises Pages, Numbers, and Keynote, all point to one thing: Documents in the Cloud.

The iOS versions of Pages, Numbers, and Keynote, all of which are now at version 1.6.1, have been enhanced with cross-device document syncing via iCloud.

The app’s original Mac counterparts have also been updated today to support the new feature, coinciding with the launch of OS X Mountain Lion.

In a nutshell, thanks to iCloud syncing, the documents, spreadsheets, and presentations you create with the latest versions of iWork for iOS and Mac can now stay up to date automatically. That means that you can now pick up on your Mac whatever iWork file you’re working with on your iOS device, and vice versa.

Pages, Numbers, and Keynote for iOS are available as universal apps costing $9.99 each in the App Store.

Note that Pages, Numbers, and Keynote for iOS can properly sync with their Mac counterparts only if the latter are the latest versions, which, in turn, require OS X Mountain Lion to be installed.
