Although most of us love our Google Maps Navigation, it never hurts to have a second option. MapQuest has unveiled their Android app, which brings free turn-by-turn navigation with voice guidance for both walking and driving, voice search, and live traffic updates. It also brings along OpenStreetMap, which allows users to make changes and updates to the map on the fly virtually anywhere. It's available for all phones running at least Android 1.6, so head on over to the Android Market to get your download on. Direct download link after the break. [MapQuest]
