In our previous post regarding jailbreak apps for new Apple TV 2G, we told you that since the upcoming SHatter exploit will be able to jailbreak the new Apple TV as well, the developers are already hard at work porting the old Apple TV jailbreak apps for the 2nd generation Apple TV. Now, we have learned further that the new Apple TV is already set up for installing applications according to the developer Steve Troughton-Smith.
You can definitely add an AppleTV to the provisioning portal, and if you give an app a UIDeviceFamily of 3 it will install on it when signed
The application definitely installs on the AppleTV, I used iPhone Explorer to verify
So, not only is the AppleTV set up for installing applications (of UIDeviceFamily 3), but the installation actually works
It seems now its just a matter of time until we see actual jailbreak apps for Apple TV 2G hitting the scene in its full glory!
