Those of us who've used a BlackBerry PlayBook will be familiar with the inevitable first-boot tutorials showing how to navigate the swipe-driven interface before we're let loose. Thanks to a series of demonstration videos leaked by BlackBerryItalia, it's apparent that we won't escape that educational process on BlackBerry 10 devices, either. The four clips show the basics of what we know the gesture experience will be like on full-touch L-series phones, including the signature BlackBerry Peek to check notifications and the unified inbox. Anyone looking for a direct clue as to what production BlackBerry 10 hardware will entail might be frustrated, mind you -- the rendered phone appears to be a placeholder rather than the L-series or a Dev Alpha B, and the device name is censored in an attempt to protect the source. That said, the clips provide a very straightforward explanation of the new interface concept and give us one more indication that RIM is closer to launch.
