Apple have just released the public beta of iOS 9 for those of you who just can’t wait until the official release. Unlike the developer beta of iOS 9, the public beta means you do not have to have an Apple developer account.. What’s more, you get the update over the air, and all future updates in the same way going forward. Signing up to the public beta program is pretty straight forward, once you’ve signed up all you have to do is download a provisioning profile on your iPhone, reboot then check for updates!
Obviously as this is a beta, is wise to try and avoid installing it on your primary hand set. Before you do so, its also wise to take a full backup of your device and it’s contents. Just incase you decide to roll back from the installation.
Once you’ve got your full backup, head over to beta.apple.com/profile on your iPhone. Once signed in with your iCloud credentials you’ll be presented with a ‘Download Profile’ button. Tap on this, accept the terms and conditions, and then follow the on screen instructions.
If you decide to roll back from iOS 9 all you need to do is connect your iPhone or iPad to your Mac or, put it in recovery mode, and restore it to the backup you made before biting the bullet… You made a backup.. Right?? If not, you can use an iPSW from iOS 8 you can grab the relevant files from http://www.ipswdownloader.com
