Jailbroken would be a plus.
Jailbroken would DEFINITELY be a plus ... because there is no publicly known jailbreak for the 3rd gen Apple TV.
Updated with 2nd gen. Didn't know there wasn't a 3rd gen jail break yet. Will a non-jailbroken 3rd gen allow me to connect to a server of mine in the US to stream US content? (I live in Canada)
