hi to all can any one tell me if i jailbreak my atv2 at my house and put it on my tv and network, can i move my atv2 box to other house and just put it on the tv and network.

do i have to jailbreak it back over again or will it work right away ???

thanks.

For jailbreaking your ATV just use Seas0nPass from here.
Take a closer look on YouTube and search for ATV2 jailbreak 4.4.4.

After installing the new firmware on your ATV2 you can access the box using ssh.
Now install XBMC like this way: [AppleTV 2] Jailbreak FAQ (NEW: AppleTV 4.4.4 jailbreak now UNTETHERED) - XBMC Community Forum
