Delayed last week, available this week. That's how Sony's Adhoc party rolls. The service - which allows PSP owners to connect their handhelds to an ad hoc internet connection through their PS3s - officially went live in Japan today, bringing joy and convenience to hundreds of thousands (and potentially millions) of Monster Hunter owners across the country. Before you ask "US release date pls", don't bother, we don't know.
