It’s been a busy day for Windows Phone OS updates. Earlier we sat AT&T customers pick up firmware and software updates for their Nokia Lumia 1020s and Lumia 1520s. The Lumia 1020 is currently getting the Lumia Black update (and an OS patch for Update 3) on Windows Phone 8, while the Lumia 1520 is getting a firmware update. Not to be left, there’s an update for the Nokia Lumia 925 on T-Mobile. What’s new?
