According to some details we’ve received from a Russian blog called iGuides.ru, , the hack involves changing DNS settings to manual (062.075.229.047) in your Apple TV’s Settings.
By changing the DNS settings, you will be able to access to UnliMovie television programming through the Trailers app. To switch back to watching movie trailers, one just needs to change from manual to automatic DNS in Apple TV Settings.
It should be noted that UnliMovie currently provides content free of charge, but not for long as paid subscriptions will launch in September. UnliMovie licenses content from several big name partners, but they don’t seem to be minding the hack.
