From Google Mobile Blog this week
Today we're launching a new version of Google Maps for mobile with the same street-level imagery available on desktop. Wondering if the restaurant in your search results is the one you're thinking of? Just click "Street View" after your search to see the storefront. Unsure about a complicated intersection in your directions? Use Street View to see a photo, so there's no mistaking your turn. You can also launch Street View from any address where we have photography, or simply by clicking on the map and selecting "Street View". You can browse Street View overlaid on the map or in full screen, rotate your view to see more of your surroundings, and move along the street.
