Get location(lat/long) without GPS, just like my location feature in Google maps. I have Google Maps in my mobile (Sony Ericsson G502 without GPS). It works fine without GPS in India.

1.How Google finds my position?
2. When i am searching cellid in opencellid database, it has less number of records for India. but Google Maps works fine in my mobile(India)
3.Is Google uses opencellid database or its own?. if Google uses its own, shall we have access to it database
