Some sites claim, they have paid jailbreaking tools as well as free jailbreaking tools to jailbreak following iDevice’s runnining iOS 6.1.3 or 6.1.4. We force you not to trust them. Actually, I have to say there is no, any tool to downgrade these iDevice’s iOS 6.1.3 or 6.1.4 yet. Even if Apple supports to upgrade iOSs of iDevice’s, they have no, any option to downgrade iOSs. We want to wait until, jailbreak tool’s developers release jailbreaking tool to jailbreak following iDevices running iOS 6.1.3 or 6.1.4. We can only expect it.
