Back in Berlin, Germany a few weeks ago during Microsoft's big reveal, many people noticed the Flipboard app for Windows Phone was preloaded on a the new Lumia 730 and Lumia 830 display phones. I won't get into the politics of what happened, but you can pretty much guess that Flipboard was not announced that day. Instead, it is still Coming Soon™.
This morning though, a link for the app has been spotted on the Store. As you may have learned from the headline, you cannot yet download it, making this likely blocked by the developers until they are ready to announce it, or it is a private beta, meant for internal testing.
