Don't Install It If You Want to Keep Your Jailbreak
An iOS 10 jailbreak is available but it's only available for select devices on select versions of iOS 10.
While there's a way to jailbreak iOS 10.2 and older versions of iOS 10, there's no way to jailbreak the iOS 10.3.3 beta. There's also no way to jailbreak iOS 10.3, iOS 10.3.1, or iOS 10.3.2.
So if you want to keep your current jailbreak, or you think you might want to jailbreak down the road, avoid iOS 10.3.3 beta.
An iOS 10.3.3 beta jailbreak isn't out of the question but there's a good chance developers will hold back for a final release.
If we're so lucky.
