Here is how to prepare for iOS 9 update

Apple is all ready for the public release of iOS 9 for iPhone, iPad and iPod touch owners across the globe. The free software update for compatible iOS devices is "the most advanced mobile operating system," according to Apple. It incorporates the overhaul Notes app, support for transit in Maps, the News app and new capabilities in Apple's mobile payment service, apart from built-in apps. Owners of iPad can now be more productive as iOS 9 brings new multitasking features, while running two apps side by side. Here are a few tips to help iOS owners prepare for the update.

Compatible iOS devices

iOS 9 will be available for all devices running iOS 8. But note that all the features in the new iOS iteration will not be available for all devices and in all countries. The following is a list of compatible devices:

• iPhone 6, 6 Plus, iPhone 5s, iPhone 5c, iPhone 5 and iPhone 4s
• iPad Air 2, iPad Air, iPad 4, iPad 3 and iPad 2
• iPad mini 3, Retina iPad mini, 1<sup>st gen iPad mini
• 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.
