Last year, when MobileMe transitioned from a pay-service to the the free iCloud, Apple gave an additional 25GB of storage to former MobileMe subscribers as a thank you. The bonus storage was supposed to be downgraded at the end of September, but in an email today, Apple said it extended the complimentary storage for an additional year, to September 30, 2013.
When you moved your MobileMe account to iCloud, we provided you with a complimentary storage upgrade beyond the standard 5GB that comes with an iCloud account to help you with the transition. Originally, this storage upgrade was set to expire on September 30, 2012.
As a thank you to our former MobileMe members, we will continue to provide you with this complimentary storage upgrade at no charge, for an additional year, until September 30, 2013. No action is required on your part. For complete details, please read this article.
Thank you again for using iCloud,
Apple notes that users received either 10GB, 20GB, or 50GB of additional storage — on top of iCloud’s standard 5GB — depending on the amount of MobileMe storage the user was paying for when the service transitioned to iCloud.
