The Samsung Galaxy S III is officially here, and Aaron's doing a (very early) review of Samsung's newest Ice Cream Sandwich superphone in London.  Galaxy S III offers a 1.4 GHz quad-core Exynos processor, 4.8-inch Super AMOLED HD (720x1280) display, 8-megapixel camera with 1080p HD video recording and burst mode, 1.9-megapixel front-facing camera with 720p HD video recording, 2,100 mAh battery, HSPA+ (or 4G LTE, depending on the market), and Android 4.0 (Ice Cream Sandwich) with the newest version of TouchWiz.  The smartphone is incredibly fluid, and has a ton of great hardware and software features that users are sure to like.
