On Thursday September 22nd Apple will reset iCloud in preparation for the beta service’s final releas, which is expected to arrive when iOS 5 leaves beta.
If you have been using the developer beta of iOS 5 on your iPhone or iPad, you won’t be able to access the backups made before Thursday, 22 September starting at 9 AM PDT.
Also, you won’t even be able to access iCloud until Apple finishes with the reset at around 5 PM PDT.
The news posted on the Apple Developer boards earlier this week and reposted by 9to5Mac says the following:
On Thursday, September 22, the iCloud Backup data will be reset. Backing up to iCloud or restoring from an iCloud backup will be unavailable from 9 AM PDT – 5 PM PDT. If you attempt a backup or restore during this time, you will receive an alert that the backup or restore was not successful. After this reset, you will be unable to restore from any backup created prior to September 22. A full backup will happen automatically the next time your device backs up to iCloud.
If you have used iCloud for backup, get your stuff backed up some other way until this reset finishes. Apple will not erase your mail, contacts, calendar, reminders and bookmarks. This only affects things like pictures, files, videos, etc. Your local copies will remain on your device, and you should be sure to perform a backup as soon as the service comes back online.
This serves as further evidence that Apple will drop iOS 5 very soon along with the release of the long-awaited new iPhone that every calls iPhone 5. We already reported the very strong possibility that October 4 will be the day Apple unveils the new device. You will likely see iOS 5 on or soon after that date meaning that iCloud could be opened up to the public about the same time.
