You know how difficult it is for jailbreak developers to find those vulnerabilities within new firmware in order to jailbreak it. Along with the first iOS 6 version released, the Evad3rs team provided us Evasion, the well-awaited jailbreak tool. Since the two versions of iOS released so far did not affect the untethered jailbreak, apparently the iOS 6.1.3 that will be released any time soon, it will patch the key exploit.
This is terrible news for jailbreakers all over the world. If you depend on your jailbroken device, then you should not hurry to upgrade your iPhone, iPad or iPod Touch to the next firmware update. PlanetBeing, a founding member of the Evad3rs team, suggests the fact that Apple has patched one of the main five exploits used by Evasion in order to perform an untethered jailbreak. Therefore, for all things to be clear for you, Evasion jailbreak will be patched in the future iOS 6.1.3.
Therefore, according to PlanetBeing, the jailbreak developer, if one of the five exploits does not work, neither does Evasion.
As a bottom line, in order to preserve your untethered jailbreak status of your iOS 6 device, you should avoid upgrading your current device to the new software update. Just in case, you should back up your SHSH blobs for a possible downgrade solution. I am sure that jailbreak developers will figure things up eventually, but until official news concerning the iOS 6.1.3 and the possibility of an Evasion jailbreak, all we have to do is to wait and see what happens.
If you recently upgraded your iPhone, iPad or iPod Touch to iOS 6.1.2 and you want to start jailbreak on it, you should check out our iOS 6.1.2 jailbreak tutorial using Evasion, the jailbreak tool.
