10 Things to Do Before Installing iOS 9.3.3 Beta

Research the Downgrade Process

If you decide you want off the iOS 9.3.3 beta know that you'll only be able to go back to the iOS 9.3.1 or iOS 9.3.2 update. Apple stopped signing off on the older iOS 9 updates which means that your only choice is to go back to one of those. Note that the iOS 9.3.1 downgrade loophole should close up soon.

It's important to get familiar with this process before you download the iOS 9.3.3 beta. If you start feeling leery about the process, you might be better off staying on a public version of iOS 9.
