Just what is the big deal about an untethered jailbreak? Well, for those who are not in the know, a tethered jailbreak means you will need to perform the jailbreak process all over again each time the device reboots, while an untethered jailbreak means doing it once only, and you will only need to perform a new jailbreak whenever a later version of iOS rolls around.
Still, it seems that there is plenty of work left to be done surrounding the untethered iOS 5.1 jailbreak where iPhone 4S owners are concerned, so iPhone 4 users are closer to the finish line than iPhone 4S owners. A little bit more patience is required here, folks, so let us give pod2g enough time for him to weave his magic.
