Even it’s possible to use redsn0w on 6.1.3, iPhone and iPod touch owners will only be able to jailbreak using what’s referred to as a “TetheredJailbreak”. Consequently, devices jailbroken using this method will require Redsnowto boot into their fully jailbroken state every time they power off. However, it is possible to install what’s known as a semi Tethered or a Semi UnTethered jailbreakon iOS 6.1.3 after completing this tutorial. This will allow the iPhone or iPod touch to reboot without the assistance of a computer with limited functionality. If you’ve previously jailbroken using a tethered version of redsn0w, jailbreaking 6.1.3 should be easy for you.
