In 2011, when iCloud replaced MobileMe, Apple gave paying MobileMe customers an additional 20GB of iCloud storage as a thank you for their purchase. That storage was to be discontinued in September of 2012, but Apple ended up giving MobileMe users another year of storage for free.
Now, however, the complimentary iCloud storage plan will be expiring at the end of next month, on September 30th.
That is going to be an uncomfortable day for a lot of Apple’s support infrastructure. Managing your iCloud storage is not straightforward.
