Apple is reportedly preparing to reset iCloud backups on September 22. The information falls nicely into place with previous rumors of Cupertino preparing to roll out the Gold Master version of its iOS 5 in the last week of September (some reports point towards September 23).
The information comes from an Apple Developer board posting that says: “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”. The post goes on sayin that “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”.
The date of the reset is more or less around the date of Apple’s releasing the Gold Master edition of iOS 5. This will be the latest release before the final version of the platform expected to debut on not one, but two iPhones coming at the beginning of October (with a possible late September announcement).
