So this happened yesterday in the CrackBerry forums. The original source is really unknown but it popped up on Instagram as well, which looks to be from the same source as the previous images shown off -- given that they share many similarities with the exception that this particular device actually has more apps loaded onto it. Though by now everyone has a general idea of what the BlackBerry 10 L-Series it will look like either way.
All that said; nothing in this image is final so take for what it is. An updated image of an unfinished device running an unknown version of an unreleased OS. Now about those N-Series devices. They'd be pretty nice to see right now since the L-Series is already out there enough.
