Hi, Just bought a new Apple TV and it is at version 4.1.1 and I have not updated it to 4.3. Looks like I need to update it to 4.2.1 to be able to do an untethered jailbreak. From googling a bit it appears that this is not going to be possible. What are my options for jailbreaking? I really would like to install XBMC on it. Thanks in advance for any tips.
