Apple was criticized after users found that Siri replies blankly on being asked for information on abortion and birth control.
Technology giant has said Siri's inability to locate abortion clinics was due to technical malfunctioning.
The American Civil Liberties Union had urged Apple to resolve the issue and enable people to find the 'reproductive resources', The Daily Mail reports.
The iPhone 4GS users, however, had no such problem, which Apple said, did not originate due to any political stance of the firm.
"These are not intentional omissions meant to offend anyone. It simply means that as we bring Siri from beta to a final product, we find places where we can do better, and we will in the coming weeks", The New York Times quoted a company's spokesperson, as saying.
One of Siri's creators, Norman Winarsky, said the problem might have originated with the web services of the company's partner firm, claiming that 'Apple probably hasn't paid much attention to all the results that come up'.
Siri users with foreign accents, especially Scottish, do not find the application user-friendly.
Late Apple co- founder Steve Jobs, who was adopted at birth, once expressed his gratitude to his biological mother for giving him birth rather than having him aborted.
