apple tv on stock 4.4.3. Possible to upgrade to 4.4.4 right now?

Hi Guys I need a bit of guidance please.

 

I have jailbroke many an apple tv2 on 4.4.4 however my mate has just ordered one off amazon however it came pre installed with 4.4.3. 

Is there any way I can upgrade to 4.4.4 at the moment? Or does a jailbreak for 4.4.3 still work ? I dont want to upgrade his to 5.1 yet as XBMC does not work yet…

 

Any guidance would be much appreciated.

 

Thanks
