Avoid iOS 11.1 If You're Jailbroken
If you want to keep your jailbreak you'll want to avoid the iOS 11.1 update (and the iOS 11.1 beta) when it arrives.
Jailbreak developers have reportedly jailbroken iOS 11, but we haven't seen any credible iOS 11.1 jailbreak news.
At this point, it's unclear if developers will release a public jailbreak tool for iOS 11.1 or the earlier versions of iOS 11.
To be safe, you'll want to avoid iOS 11.1 when it arrives. There's always a chance developers release a jailbreak for an older version of iOS 11.
