10 Things to Know About the iPhone 6s Plus iOS 9.0.2 Update

No More iOS 9.0.1 Downgrade

For a short period after Apple offers a new upgrade, the company also offers an option to downgrade to the older version. 

Up until late last week you could install iOS 9.0.2 on the iPhone 6s Plus and if you ran into some type of problem you could downgrade to iOS 9.0.1. the process is not as simple as an upgrade, but it was possible. 

You can no longer downgrade from iOS 9.0.2 to any older version of iOS, so if you install this update you need to live with it until iOS 9.1 arrives. There is no major problem with iOS 9.0.2 on the iPhone 6s Plus that makes this an issue, but it is worth noting.
