Jest to w dalszym ciągu Tethered JB:
I kolejny mój kopiuj-wklej post:

-"The final build of iOS 6.1.3 has made its way to the end-users, with bug fixes and improvements over the prior release. Those who are more interested on customizing their devices by jailbreaking, then there’s both good and bad news.
Apple has patched Evasi0n untethered jailbreak exploits for iPhone 5 and other newer devices. So if you accidently updated to 6.1.3, there is no way for you to untether-jailbreak your device.For never devices, there is no option to downgrade to older firmware either. But if you happen to have A4 powered iOS device, you can tether jailbreak iOS 6.1.3, full details after the jump.
We have tested and can confirm that using the latest version of Redsn0w, a tethered jailbreak can be applied on all pre-A5 iPhones and iPod touches, those vulnerable to the Limera1n exploit, such as the iPhone 4, iPhone 3GS and iPod touch 4th-generation. Unfortunately, as mentioned above, newer devices like the iPhone 5, iPhone 4S, iPad and iPod touch 5th-generation cannot be jailbroken."
