Not that it matters, but it's Windows Phone 7.5, not 7.1
Earlier this morning, a bunch of tech sites ran with a "Mango is Windows Phone 7.1, not 7.5" story, citing one section of the WP developer site with placeholders front and center. We didn't run it because it seemed to not be an accurate reflection and we've seen quite a few 7.5 references that cannot be so easily dismissed.
Long story short, in the newly released Mango emulator, the "About" screen clearly shows Windows Phone OS 7.5, putting to rest any doubt. (Or is it, perhaps Microsoft is just toying with our nerdy fascinations?)
But as the title says, it's not like it really matters in the end.
