Apple has just released iOS 9, and as with any new software update, it comes with a number of new features and bug fixes. If you’re like most people, you’ll want to update your iPhone 4 to the latest version as soon as possible. To do so, you’ll need to first make sure that your device is up-to-date by going to the Apple website and clicking on the “Updates” tab. From there, you’ll need to select your iPhone 4 model and then click on the “Update Now” button. Once your device has been updated, you’ll need to reboot it in order for all of the new changes to take effect. After your device has restarted, you should be able to see the iOS 9 logo in the top left corner of your screen and be able to access all of its features.
