What iOS can be jailbroken?

Is there a list of the iOS that can be jailbroken for atv 1? Can’t seem to find it or are they all jail brokenable? I have 3.0.2

The ATV1 doesn’t actually require a jailbreak, and the current version of aTV FLash (http://firecore.com/atvflash) will include everything you need for the 3.0.2 software.
