Apple Ends Complimentary 20 GB Storage Plan for Former MobileMe Members
As noted in an Apple support document, affected members will be downgraded to the 5 GB storage plan that is offered free with iCloud. Apple also offers extra storage plans for iCloud users, with an additional 10 GB of storage for $20/year, 20 GB for $40/year, or 50 GB for $100/year.
Users who are currently over the free 5 GB limit following the expiration of the complimentary 20 GB will see such features as iCloud Backup, Documents in the Cloud, and iCloud Mail cease functioning until they bring their accounts under the lower 5 GB limit.
Apple replaced MobileMe with iCloud in 2011, giving paying MobileMe customers an extra 20 GB of iCloud storage as a complimentary gesture. The additional storage was originally set to be discontinued in September 2012, but Apple decided to extend the offer, giving MobileMe users another year of extra storage free.
