Hi!
I am utterly confused.I want to buy a mobile handset that should have all the general features.Along-with that I need tracker that can be used to locate my relatives whenever I need or they needed.I have heard about the GPS technology.Please suggest!!!!!
GPS or Global Positioning System is a technology that will tell you exactly where you are (latitude and longitude). It is able to do this because there is a chip in your GPS device or GPS enabled phone that is able to get your current location from a network of orbiting US satellites. It is usually integrated with a mapping software service so that you can see where you are in a map. Good GPS services will also give you driving directions if you enter your destination.
Considering that Indian roads generally have very few sign-posts and navigation is usually done by asking a chai-wallah or a pedestrian or an auto driver, GPS is actually incredibly useful, especially for people who travel a lot. A dedicated GPS device is the best way to go. mapmyindia is highly regarded and has good pre-loaded maps.
However, GPS will not tell you where your relatives are.
Perhaps, what you are looking for is this:

An alternative to GPS is a location based service offered by telecom companies that detect your cellphone location by triangulation (comparing your signal strength with three cellphone towers and using this to calculate your approximate position).
