Interactive maps let you zoom in or out, and move in all directions so you can orient yourself visually. You can also get a satellite images for the maps as well.
They also offer real time traffic information, local business listings and driving directions but is not available for India yet. Currently all these features are available only for Australia, Belgium, Canada, France, Italy, Germany, the Netherlands, Spain, the United Kingdom and the United States.
Well for India at least we can see the city maps. Another good feature about this application is Insta-KB-o-meter, where you can see the real time information about your data usage so that you can find out how much its going to cost you.
Another good thing is, if you have GPS receiver for your smart phone, you can use this application as GPS device. Isn't that cool ?
