You Don't Know Jack will land on iOS in the "very near future," Jellyvision announced on their Facebook page. The announcement was coupled with the appropriately demeaning video seen above.
Jellyvision began testing the Android version of the game recently, so no solid release date was announced for it. Not that "the very near future" was helpful for iPhone and iPad users looking to get their trivia on. The mobile versions of You Don't Know Jack were first announced in April 2011.
