What devices can use iOS 9?

iOS 9 is available for the following devices:

iOS 9 is not available for the iPhone 4, iPhone 3GS, original iPad (released in 2010), or previous generations of the iPod Touch. If you use one of these devices, you'll still be able to use your existing version of iOS. Keep in mind, however, that your device may experience performance issues if you download apps from the App Store designed for iOS 9.

Am I required to upgrade to iOS 9?

While it's not required, we recommend upgrading your device to iOS 9 if possible. This will help keep your phone up to date and working with newer apps.

If I don't upgrade, will I still be able to download newer apps?

Yes, but some apps may not always work correctly. If you don't upgrade to iOS 9, you may want to research how well an app will work on your device before downloading or updating it.

Even if an app has always worked perfectly on your device, there is a chance that the newer versions may only run smoothly on iOS 9. You may want to avoid updating your favorite apps unless you are sure they will work with your device's operating system. Once you update an app, you won't be able to go back to an older version.

Will my apps still be there after I upgrade?

Yes. Any app you previously had installed on your phone will still be there once you upgrade to iOS 9. Some built-in Apple apps, like Messages and Calendar, will be updated automatically when you upgrade.

Will my apps still work after I upgrade?

Almost all apps installed on iOS 8 should work correctly in iOS 9. If not, the app developer will likely release an update to address the issue.
