iOS 8.4.1 Jailbreak
There is no iOS 9 jailbreak so if you're jailbroken, do not upgrade to the iOS 9.0.1 update. It's not clear when an iOS 9 jailbreak will be released and it could be weeks or even months before one is released.
In the meantime, we could see developers release an iOS 8.4.1 jailbreak. A release date is set in stone but we know one is in the works. Keep an eye out if you want to jailbreak your iPhone 5s.
