iCloud stops working for users over base 5GB tier
In keeping with warnings, Apple has today stripped former MobileMe subscribers of an earlier free upgrade to the 25GB iCloud tier. The upgrade was offered to help ease the transition to iCloud, since MobileMe was a paid-only service that included 20GB of data, or more under a family plan. iCloud has both free and paid tiers, but the free one only includes 5GB. The 25GB option normally costs $40 per year.
Apple cautions that if a person is over the 5GB limit after the transition, they will be unable to use iCloud unless they delete enough data or switch to a sufficient paid plan. Beyond the 5GB and 25GB tiers, people can also choose from 15GB ($20) and 55GB ($100) subscriptions. Upgrades can be made through iCloud's Storage & Backup menu in the iOS Settings app, the Manage section of OS X's iCloud settings, or the iCloud Control Panel in Windows.
