Apple recently announced during their media event that iOS 9 will be released on September 16th. The firm also released iOS 9 GM to developers so that they can submit their iOS 9 apps to the App Store for registration and approval.
In addition, since this is the final iOS 9 version, users can install iOS 9 right now. According to iPhoneHacks, the source says you won’t need a Developer UDID registration or any other type of public beta profile, but folks will need to get the appropriate iOS 9 IPSW file for your iOS device.
Furthermore, before you decide to get iOS 9 GM, iPhoneHacks posted up some notes to go over before you download it:
- Even though its iOS 9 GM, the public release is likely to be the same build number, and the risks associated with installing the beta version are reduced, please proceed with caution.
- You should avoid downloading the iOS 9 IPSW file for untrusted sources. You run the same risk as downloading any other software such as malicious software etc. Your best bet is to get the iOS 9 IPSW file from a trusted source such as a friend who is a registered iOS developer.
- It is very important to take a backup of your device using iCloud or iTunes, so you can restore your personal data if something goes wrong during the update process.
Assuming you were able to get the iOS 9 IPSW file, you will need to follow these steps that the source also posted to upgrade to iOS 9 on your iOS device.
- Double click on the zip file to extract the iOS 9 IPSW file.
- Open iTunes.
- Connect your iPhone, iPad or iPod touch to your Mac or Windows PC and launch iTunes.
- In iTunes, select your iOS device from the top left corner and navigate to the Summary tab.
- Hold down on the Option key (or the Shift key in Windows) and click the Update iPhone… (iPad or iPod touch) button.
- Now select the .ipsw file from the extracted folder to install iOS 9 beta and click on the Open button.
- iTunes may prompt you that it will update your device with iOS 9. Click Ok to continue.
- You will get a ‘Slide to upgrade’ slider after it reboots. Swipe on the slider to proceed.
- Your device will reboot again, and you’ll be greeted with the ‘Hello’ welcome screen. Swipe on the ‘Slide to setup’ slider and tap on Continue and follow the on-screen instructions to setup your device.
That’s it, you should be upgraded to the official version of iOS 9.
It should be noted that since the build number of iOS 9 public release should be the same as the GM build (13A340), you shouldn’t have to do anything when iOS 9 rolls out on September 16th.
