Those of you who have already updated iPhone and iPad devices to iOS 9.0.1 and 9.0.2 versions can no longer downgrade to the older versions, iOS 9 and 8.4.1 as Apple has stopped signing these versions.
We had earlier written that users of iPhone, iPad and iPod touch should downgrade from iOS 9 to iOS 8.4.1 as soon as possible because they can't do so once Apple closes the signing window of the older version.
A report by 9to5Mac has now confirmed that the Cupertino giant has stopped signing iOS 9 and iOS 8.4.1, which means one can't downgrade to these versions anymore. But Apple still signs iOS 9.0.1, so users who are not happy with iOS 9.0.2 can downgrade to the older version.
However, everything should be fine as the latest version, iOS 9.0.2, is said to have fixed almost all the problems spotted in the earlier versions. It came with several bug fixes like cellular data usage switch, iMessage activation, iCloud backup, screen rotation, Safari browser, Photo apps and custom APN setup.
Interestingly, Apple released iOS 9.0.2 firmware update before iOS 8.4.1, iOS 9 and 9.0.1 were jailbroken. So, it won't come as a surprise if TaiG, Pangu and other developers skip jailbreaking these versions and work on iOS 9.0.2 jailbreak instead.
