Apple Officially Ends MobileMe Transition and Shuts Down iWork.com
As of today, visitors to MobileMe.com are no longer given the option to convert their accounts to iCloud or to retrieve old photos and files, with Apple now simply pointing users to iCloud.
Also in line with previous announcements, Apple has officially discontinued its iWork.com service, automatically redirecting visitors to the main Apple home page. While the service was to officially shut down as of the end of the day yesterday, it did continue to function until just a short time ago.
We noted yesterday that Apple was unlikely to provide a grace period to allow users to retrieve iWork.com documents after the official discontinuation date, and that does indeed appear to be the case.
