The beauty of this jailbreak is that it is completely cable-free. All you need is an activated device (iPhone) or iPad or iPod Touch. If you are stuck at bootscreen or see a cable on the screen, you have to try some other tools (TinyUmbrella/blackra1n/limera1n) depending on the iOS version. This jailbreak is untethered too meaning you don’t have to worry about running out of charge or rebooting the device.
If your iDevice isn’t jailbroken yet, head over to jailbreakme.com on your iDevice and slide to jailbreak!
