Apple is sending out reminders to users currently enjoying 20GB of free iCloud storage warning that their accounts will be downgraded unless they take action, notes “The Next Web” (

This meant that users switching from MobileMe to iCloud received a total of 25GB storage space (including the free 5GB offered to new users). Now if they don’t free up space and come in under the 5GB free limit or pay for the extra storage, apps will no longer back-up documents to iCloud.
