At this time there is not a jailbreak utility that currently works on the latest public firmware (being iOS 9.0, at this time). Jailbreakers should have hope because there are three groups working on a jailbreak. The groups are Pangu, TaiG, and K33n.
As some people already know iH8sn0w jailbroke an iPhone 5 running iOS 9 GM using a low level bootrom exploit. Sadly this method does not work on 64 bit devices. iH8sn0w says that he doesn't plan on releasing a jailbreak utility for iOS 9.
In conclusion, avoid iOS 9 at all costs. Do not update your iDevice OTA either because that will mess up future jailbreaks. For more updates about jailbreaking follow us on Twitter @iKillTheApple
