Yesterday I told you that a new exploit allows to perform a untethered jailbreak for iOS 6.1.3, but unfortunately I didn't have much information about him. Well, during this night the hacker who discovered it stated that it can only be used for the time being on the GSM version of the terminal iPhone 4. Its discoverer claims that other iDevices are not compatible with it and there is probably little chance that we will be lucky enough to benefit from it because iPhone 4 it is also exploitable through a bootrom exploit.
Basically, you have to understand from this that this exploit has an extremely limited utility and even if it will be released, it will be usable on a limited number of terminals. It was normal not to have one untethered jailbreak for all running iDevices iOS 6.1.3 and it was normal to have problems of this kind, but for many this will matter too little since iOS 7 it will be available in a very short time and many will update without thinking too much.
