iPhone 4s iOS 9 Release: 10 Things to Keep in Mind

Watch for App Updates

In the buildup to the iOS 9 release date, keep an eye out for new app updates with support for the iOS 9 release. 

These updates should help your apps make a smooth transition from iOS 8.4.1 or below to iOS 9. We typically install all of them ahead of release day and we typically come out of the release date without any major problems. 

Before you install, make sure you read reviews about the current version to make sure the bug fixer didn't screw anything up. Developers went through a lengthy beta so the odds of that happening are slim.
