You can fly like Superman around buildings on the amazing new UpNext NYC iPhone app. Google might offer a great Streetview of Manhattan, but this young NYC startup has come up with something that's on, well, a higher level. As you zoom thru Manhattan you can tap a building to see what's inside or search for bars, restuarants, hotels, etc. In the Top 20 in the Travel section of the iPhone app store. It's worth more than the $2.99 fee.
