It can not be avoided that Nokia Maps (aka Ovi Maps) are the most anticipated maps and navigational services around the world amongst any other Maps and Navigational services on any platform. Nokia previously made its web based maps available to HTML5 enabled browsers which directly facilitated Android and iOS devices, nonetheless with fewer features. Now a big and most awaited Nokia Maps on Windows Phone has been appeared with its full formed native app in Marketplace.
Nokia Maps have been optimized fully with HTML5 which lead the awesomeness of Nokia Maps through Apple's iOS and Google's Android.
Nokia has recently launched an HTML5 powered version of Nokia Maps which runs on an HTML5 browser just like a native app, including iPhones and Androids.
I've selected a few areas in Lahore and Karachi to add some places. But before start adding them I want to inform you that the editing system doesn't seem to be perfect yet on Ovi Maps. Hope Nokia will be on it right now making it more user friendly. But I don't want to give you hopes for it to be as good as Google Map Maker. However adding places is quite quick once you find a correct location on map.
