Hot off the heels of the Windows Phone 7 "Mango" event today -- which was eerily missing turn by turn navigation from the announcement -- a video of the feature in action has leaked, confirming the navigation upgrade for the platform.
The turn-by-turn navigation appears to contain voice based directions and auto-recalculates based on the journey changes.
The video comes from the Mango emulator which was released with the SDK today, and appears to work but is still very buggy. Is the Windows Phone 7 "Mango" emulator unlocked already?
Developing Story... More soon...
