We had heard that the introduction of the BlackBerry Bold (9000) / Thunder (9500) could usher in the long-awaited BlackBerry OS 4.6, and now we're just about ready to believe it. A new listing over at Horizon Wireless Online details the forthcoming operating system, and notes that it will bring along richer browsing (which entails a whole host of improvements), click zooming with the trackball, Music Sync, an option to select Home screen grid size and support for continuous spell checking (among other things). Hey RIM, can we get that "richer browsing experience" on say, the Curve / Pearl?
