Samsung’s Galaxy S2 will arrive in the U.S. starting September 16 with the Sprint Epic 4G; the S2 rollout will continue with T-Mobile and AT&T models later in the fall. Verizon – at least for now – is the only carrier passing on the follow-up to the popular Galaxy S.

All models will feature a Android 2.3 “Gingerbread” running on a 1.2GHz dual-core Samsung Exynos ARM processor, have 1GB of RAM, large AMOLED+ touchscreens, 8MP cameras with 1080p video capture, 2MP front-facing cameras, 802.11n Wi-Fi, and Bluetooth 3.0.  The three S2s will also have similar designs, but with varying size and weight.

The AT&T Galaxy S2 (left) will have a 4.3-inch AMOLED touchscreen and 16GB of flash storage; the Sprint Epic 4G (center) and T-Mobile Galaxy S2 (right) will have larger 4.52-inch touchscreens.  All have microSDHC memory card slots for up to 32GB microSD cards.

The only price announced is for the Sprint Epic 4G, which will sell for $199 with a two-year contract.
