A few small changes have occurred on Windows Phone 7. First and foremost, Windows Phone 7 now features an emulator for testing. This simulator should be treated like those on other platforms in that you'll get a rough idea of the how the app should run, but this should no means replace a physical hardware device.

Also a bug that was causing inaccurate analytics on Windows Phone 7 Apps has been resolved. App session stats are now separate from download stats.
