If you haven't checked out the latest app from Microsoft to hit the iPhone, do so now. It offers multiple app check in goodness but that's not all! First is that it includes Facebook integration but the kicker is Bing Streetside. Straight from the Press Release:
Familiarize yourself with a location before you go, using Bing Streetside. Streetside, a new mapping feature, gives you a multi-street level panorama of a location so you can take a virtual walk through the streets with a view of a location and its landmarks. Slide the street level imagery sideways, and the view of the sidewalk is seamlessly constructed, including an overlay of business listings, street names and store fronts.
