iOS 9.3.5

iPhone owners looking to downgrade from iOS 10 to the previous version (iOS 9.3.5) are out of luck. This week, Apple stopped signing the latest iOS 9 firmware. This means that downgrading to the earlier operating system is not possible. At this time, the only versions of iOS that can be installed are iOS 10.0.2 and 10.0.3. Apple released iOS 10.0.3 exclusively for the iPhone 7 and iPhone 7 Plus. For all other iPhones iOS 10.0.2 remains the current version.

Apple has patched an important security vulnerability with the release of iOS 9.3.5. The iOS update comes just weeks after iOS 9.3.4 closed off the Pangu jailbreak earlier this month. Details regarding the latest security fix have surfaced and Apple has released an official security document on the matter. So should iOS users rush to update?
