We heard about build 8200 of Windows Phone 7 floating around recently. The build was speculated to be the next iteration of the OS after Mango. Code-named "Tango" (keeping up with the "last letter is O" naming) build 8200 and beyond are thought to be another interim release bringing new features, bug fixes and act as a hold over till "Apollo" aka Windows Phone 8 hits.

Indeed, it looks to be the case and what you see to the right is reportedly a shot from the OS. Specifically you're looking at "Content Search" or rather the OS's ability to first search within the device before going to the Web i.e. it's basically a global search tool:

"Content Search (Build 8200 Tango), it more or less works, first it´s finding content directly on the phone, and then on the web, the good thing is that Facebook pages work now (finally), i don´t know about twitter/LinkedIn, i haven´t them synced up, voice activated searching is also possible, similar function what iPhone has."

Pretty impressive as a new feature and it shows that Microsoft is barreling down on the OS, pumping out builds as fast as they can complie them. Good news for us.
