Apple Shuts Down MobileMe, Data Available for 'Limited Time'
As promised, Apple has shut down the MobileMe web service but is still allowing users to migrate their data for a "limited time". Apple had been sending out warnings to users of the impending shutdown.
Apple announced the planned discontinuation of the MobileMe service last year. Apple expects users to migrate to their iCloud service, though not all services have been transitioned to the new service.
