Can the Xbox be used without Xbox live?

it can. But i think you need to set it as the Home Console first before using it offline.

I remember you having to update the Xbox before you can use it for the first time.

But these tweets make it sound like people have already set up their xbox and have been using them in the past.

I'm not sure about that. Personally even during this black screen problem i could still play games.
