Research In Motion just recently released an update to the BlackBerry 10 beta operating system. Developers can install it on their BlackBerry 10 Dev Alpha A. Or, it comes pre-installed for those who received the BlackBerry 10 Dev Alpha B.
However, we’ve discovered that hidden in the beta OS is a tutorial video that shows the bottom section of what we’ve seen to be the final BlackBerry L-Series.
This tutorial video was hidden, but accessible through an options panel in a side-loaded Android app. Nonetheless, this looks like a near confirmation that the L-Series will look just like the leaked images.
