In the video above Blaise Aguera y Arcas of Bing is demonstrating a new Photosynth application for iPhones. The application is expected to be released in the coming months.
It looks like Photosynths captured with the iPhone could be added to Bing Maps. In the second half of the video Blaise demonstrates Street Slide. Street Slide is a side on view of a road, which can be scrolled left and right. If you zoom in Street Slide seamlessly integrates with Street Side (Street View) views.
Street Slide is available in the lastest version of Bing for iPhone.
