Accordint to that thread http://forum.firecore.com/topic/3418 I have understand that with the version 5.3 (iOS 6.1.4 - 10B809) i can change my tethered jailbreak to an untethered jailbreak.
When i am looking in the ATV2 Menu i have currently the version 5.3. (6105)
What means this (iOS 6.1.4 - 10B809) in the abvoe thread?
And what means this (6105) in my ATV2?
And the final important question => I am able to use the Nito TV 5.3 / 6.1.4 Unteher option?
