Apple’s free 20GB iCloud deal with former MobileMe users officially set to expire

Former paying MobileMe customers: your time of using 20 GB of iCloud storage for free is coming to an end very soon. You knew this was coming eventually, and Apple(s AAPL) has now confirmed it in an email to customers, sent Thursday.
The offer, which was given to those who had paid for iCloud’s predecessor once the service was shut down in favor of iCloud, expires on Sept. 30. From an Apple email:

When it expires, your iCloud storage will be automatically adjusted to the free 5 GB plan. Note that you are currently using 6.46 GB of storage. If you exceed your storage plan on September 30, 2013, iCloud Backup, Documents in the Cloud, and iCloud Mail will temporarily stop working.

Apple offers up to 5 GB of iCloud storage for free. After that, there are varying storage plans that bring a monthly fee. For former paying MobileMe users on this plan, your choice is either to knock down the amount of stuff you’re storing in iCloud to less than 5 GB — somewhat unrealistic and obviously a pain if you were taking advantage of all 20 GB — or pay up for the amount you are using.
Despite Apple’s ongoing issues with its cloud-based services, the company continues to sign up more users at a steady clip. As of the end of June, Apple reported it had more than 320 million users registered since its debut in fall 2011.
