When buying a phone in China, part of the cost is the service and installation of software that you'd like. As the price differential is so great and the international boundaries so weird, oftentimes the store you buy your phone from will preload any international software you'd ever want, any custom keyboards, any custom anythings you'd like. When iPhones were not actually sold to the Chinese market, there still were grey-market iPhones everywhere being jailbroken and localized via custom jailbreaking services. In fact, it appears some of the more recent jailbreaks have come from within China first (or 'first not sold to security companies'). [google: Pangu iOS]
