In its latest bid to capture more of the mobile search market, Microsoft yesterday launched a new version of its Bing search engine (Bing 2.0) for Apple’s iPhone, adding new features, such as camera search and Streetside view, as well as a revamped UI.

Bing 2.0 puts a heavy emphasis on deeper social networking integration, touting “check-ins” for Facebook, Foursquare and Windows Live Messenger without leaving the application.

Streetside is a new mapping feature that gives users a multi-street level panorama of a location so they can take a virtual walk through the streets with a view of a location and its landmarks.

The new Bing app can be downloaded for free at the iTunes App Store. Microsoft also launched an updated version of Bing for Mobile for Android, available through the Android Market.
