Well, there goes the rest of LG's annoyingly gradual tease campaign: the next generation LG Chocolate BL40, with a 4-inch, 800x344 (21:9!), multitouch screen has been revealed in full in a leaked promotional video.

On top of the display, we can see a few more of the rumored specs confirmed: LG's in-house Active Flash UI, Wi-Fi, 7.2mbps HSDPA, a-gps, and a 5mp camera with flash all make appearances, and we get a healthy look at the phone's software, glimpsing the onscreen keyboard, browser, Google Maps app, card-based contact system, scheduler and email app.

In terms of usability, the ultrawide screen is the obvious wildcard, but the OS will be a equally—if not more—important factor. In combination with the promise of a multitouch glass capacitive touchscreen, the simulated screen images in the video inspire confidence, exhibiting smoothness, thoughful navigation and an eye-and-finger-friendly UI in most places, although without a proper smartphone OS, the Chocolate will still be a dumbphone at heart.

As for when we'll actually find out if this thing has the wherewithal to match up with its ostentatious wackiness, all we get is a vague "coming soon," which according to previous reports, means August—though it's not clear if that's the official unveiling—which is pretty much ruined now—or the date of actual availability.
