Mystery solved - Nokia Maps will appear for other Windows Phones, but without free voice navigation
It won't feature the free voice-guided offline navigation that Nokia is keeping exclusively for its Lumia line, like the 800 and 710 phones, in the form of a preinstalled app called Drive. Nokia Maps for Windows Phone will feature local POI details (address, phone number, reviews, and photos of up to 25 locations in your vicinity), deep link support, where you can pin destinations to the Start screen, and detailed maps in satellite, 2D, and 3D views (where available).The catch?
It doesn't come as a huge surprise that Nokia wants to keep its main differentiator in the Windows Phone world for itself, but Nokia Maps is also a pretty useful piece of software, which will benefit others for free, so no complaints. The best part is that it covers most countries worldwide, so it can fill the huge blank spots that Bing Maps leaves behind.
