The LG Optimus Black may finally make its way to the United States this fall, according to a leaked internal roadmap obtained by BriefMobile. Sprint could be prepping to launch the device, model number LS865, on October 2nd. It will also offer the Samsung M930, which is expected to be the successor to the current mid-range Samsung Transform handset, as well as a new Franklin USB mobile broadband device. If Sprint does launch the LG Optimus Black, also known as the P970 abroad, it could be shadowed by Samsung’s forthcoming and more powerful Galaxy S II handset. The Optimus Black packs a 4-inch 800 x 480-pixel resolution NOVA screen, a 1GHz single-core processor, a 5-megapixel camera, and more. Read on for the leaked roadmap image.
