  • iPod touch 6<sup>th gen and 5<sup>th gen

Get latest iTunes version

Do not forget to update to the latest version of iTunes 12.2.2.

Create a backup for your iOS device

It is recommended to create a backup of your iPhone, iPad or iPod touch before you go ahead and install the update. You can do it either using iCloud or iTunes.

Note for jailbreakers

If you have jailbroken your device and are fond of jailbreak tweaks and apps then avoid iOS 9, as after the stock iOS update you will lose your jailbreak. Recently, popular jailbreak developer iH8sn0w posted a video demonstrating iOS 9 jailbreak on an iPhone 5 model.

Free up space

It is always a good idea to delete unwanted apps, which you can do by going to Settings>> Usage>> tap on the app you wish to remove. Also, keep in mind that the iOS update occupies about 1.3GB of your storage, so make sure that you have enough space to make room for the new update. Delete all that you think is unnecessary stuff.

iOS 9 installation

The iOS 9 will be available for download via iTunes and an over-the-air update. For this, you will not have to plug in your phone to the computer. If your iOS device is jailbroken, you will not receive OTA, as it would be disabled. So you will have to update via iTunes.

Release time worldwide

Apple will release the update at 10am PDT/ 1pm EST. Previously, Apple released iOS 7 (in 2013), iOS 6 (in 2012), iOS 5 (in 2011) and iOS 4 (in 2010) at the same time, observes iPhoneHacks.
