The leaked-to-all-hell BlackBerry Onyx may have undergone one last change before manufacture: judging by this shot nabbed by BlackBerry Underground, it'll also have a Curve 8520-esque optical trackpad.
This feature has been a persistent rumour since the original Onyx shots hit the web, though the fact that it contradicted the actual photos of the device didn't do much to convince us of its credibility.
In the context of early reactions to the Onyx leak, this apparent late change makes a lot of sense: the handset was characterized as a best-of-all-worlds device, keeping all the best features of non-touch BlackBerrys without sacrificing compactness. Grabbing the optical trackpad from the 8520, then, is an obvious move. [BlackBerry Underground via BGR]
