AT&T has just announced the Skyrocket HD at its Developers Summit. Technically it's called the Galaxy S II Skyrocket HD, and it's one of AT&T's first LTE devices. It's got a 1.5 GHz dual-core processor, removable battery, AMOLED display, and an enclosure described by AT&T chief Ralph De La Vegas as being "razor thin." There aren't any other announced specs, but official press images reveal an 8 megapixel rear camera and a front-facing companion of unknown resolution.
