Retrieving the Cell Site Id, Mobile Network Code, Mobile Country Code

Hi,
I am using CLLocationManager to retrieve the latitude/longitude of a place.Its working fine.I can also find the distance travelled between the old location and the new location.
But I need to get the information about the Cell Site Id, Mobile Network Code, and Mobile Country Code .
Is there any API in the SDK to retrieve them ?or any other work around that will fetch these values?

Any suggestion or help will be appreciated.
Thanks
