I have two ATV2's that are jailbroken with XBMC and one that is not and has been upgraded to the latest version of iOS. Can I sell that last one for just as much, or does the fact that I've got it on the latest version of iOS mean that it can no longer be jailbroken as well/easily (e.g., not jailbreakable at all or needing a tethered jailbreak)?
I personally don't care anymore about having jailbroken ATVs, so I'd just as soon cash in while there's money to be made. I have a separate Acer Revo 1600 ION nettop that I use for playing my Blu-ray .MKV rips, and I need 1080p in my main movie room. If the ATV3 gets jailbroken (or Apple allows 3rd party apps), I'd be interested in getting Plex installed on that, but I'd still probably stick with the Revo in my main movie room since I want 24hz support and I suspect that a hardware limitation of the CPU/GPU Apple uses will keep that feature from ever appearing in a software update.
