Meanwhile the redsn0w tool has been updated for iOS 6.0 and a tethered jailbreak is available for devices running an A4 or low processor. These include the iPhone 4, iPhone 3GS and iPod Touch 4 running iOS 6.0. You can find a step-by-step guide here.
Anyone with a new iPhone 5, iPhone 4S, iPad 2 or the iPod Touch 5 will have to wait for those devices to be welcomed into the ‘jailbreak’ world.
Developers like Grant Paul work hard to give users the freedom to use their iOS devices the way they want to, and they offer these solutions for free. So all we can do now as a user community is to be patient and wait until they are ready with the solution.
