Jailbreaking/updating an older firmware version

Hello,

I have an apple tv2 which is still running version 4.1 (as reported through the settings menu on the apple tv2), and I wish to jailbreak it. Is there a way to jailbreak it and update to one of the firmwares supported by an untethered jailbreak at the same time? Or do I have no choice but to update to the latest 4.3 and wait for untethered jailbreak to be released for it?

Thanks!

Nevermind, I bit the bullet and upgraded to 4.3 (2557/8F455) and I’ll wait until the jailbreak catches up.
