Maybe for some but I didn't use cydia or anything like that. My ATV2 iOS4.0 came out of the box and onto my Network it said there was an upgrade available so I upgraded it to iOS4.3.
It was only on 16/03 that I tried to downgrade it and it worked using the method @svela posted. So no previous jailbreaks or host entry points on the cydia server in my case.
So not always the simple reason.............
