The hack shown off in the following video, posted on Reddit, is the one wincom showed off before on iPhone 5 running iOS 6.1.4 untethered jailbreak.
There's still no ETA for this jailbreak release! We also hope that this hack works on iOS 7. Most probably hackers will start developing this on iOS 7, if it worked, they'll release iOS 7 jailbreak. If not, then iOS 6.1.3 / 6.1.4 untethered jailbreak will be released.
The evad3rs team are also already working on iOS 7 jailbreak. Stay tuned for more jailbreak news! Redsn0w is the best ;)
