IP Cam View for Windows Phone 7 or higher, free to try, $1.99 to buy. Available from the WP market page at: http://www.windowsphone.com/en-us/store/app/ip-cam-viewer/e764b794-60e8-df11-9264-00237de2db9e. Just video, no audio. Includes several public webcams as well. It took me a while to get it to work on 3G but it was not the fault of the app, it was my fault for changing the default IP address of the DCS-932L. However the manual from D-Link could have included a warning on this topic. I think a company of the size of D-Link should have an app for Windows Phones.
