AppleTv 2 with 4.4.2 already installed. Will I be able to downgrade to 4.3?

I’m about to purchase an ATV 2 for my old roommates…

I can only find it (Brand-new In Box)  with firmware 4.4.2 already installed. Will i be able to downgrade to 4.3?

My roommates are technologically challenged and tethered starts will discourage them from using this xmas present for them.

(Also while I’m here… can iPod touches be used as remotes for the ATV and do Canadian users have any limitations in terms of plug-ins and content that can be viewed?) 

Yes, simply run the current version of Seas0nPass and it will install the 4.3 version, which is untethered.
