It's no secret that BlackBerry has been in talks with many organizations to get apps onto the BlackBerry 10 platform. Thus far, they've done a great job with what they've announced and there's no signs of that momentum slowing down. With that in mind, it's starting to look like they may have a few unannounced companies onboard as well as witnessed in a video from the official BlackBerry France YouTube channel.
In the video above while demoing the Europe1 app, you can briefly spot Flipboard as one of the icons on the screen before the Europe1 app launches. Realistically, there is nothing stopping Flipboard from running on BlackBerry 10 right now.
In fact, I have it installed as an Android port on my BlackBerry Z10 and it works great but it sure does seem odd that it would be sideloaded and then not removed from an official BlackBerry video unless there was something a little bit further going on here. We'll leave it at that I guess since there is no official details. Thanks, @Skinofino!
