After months of waiting, the U.S. variants of the Samsung Galaxy S II have finally been unveiled. Both AT&T and T-Mobile are sticking with the Galaxy S II branding, while Sprint has opted to name their model the "Epic 4G Touch." Obviously there's a lot of information to digest here, so we're going to break it all down bullet point style:

• AT&T's Samsung Galaxy S II features a 4.3-inch Super AMOLED Plus display, 1.2GHz dual-core Exynos processor, 8-megapixel camera with LED flash and 1080p HD video capture, 2-megapixel front-facing shooter, 16GB storage, 1650mAh battery, HSPA+ connectivity, HDMI out, and Android 2.3 running beneath Samsung's TouchWiz 4.0 UI. Expect the AT&T GSII to hit sometime "in the coming weeks."
• Moving onto the Sprint side of things, we've got the Epic 4G Touch. Specs are similar to what we saw leak earlier today, meaning you're looking at a 4.52-inch 800x480 Super AMOLED Plus screen, 1.2GHZ dual-core Exynos processor, 8-megapixel camera with flash and 1080p video capture, 2-megapixel FFC, 16GB storage, 1800mAh battery, WiMAX connectivity, Mobile Hotspot support for up to eight devices, and Android 2.3 Gingerbread alongside TouchWiz 4.0. The Epic 4G Touch will be the first GSII variant to hit the States when it launches on September 16th for $199.99 with a two-year contract. If you absolutely, positively need to be the first on your block with a E4GT, you can mosey on down to local Sprint store and pre-order your device with the purchase of a $50 Sprint gift card.
• Finally we've got the T-Mobile Samsung Galaxy S II, which is packing a 4.52-inch Super AMOLED Plus display, just like its Sprint-branded brother. That's the only feature that T-Mobile's officially announced for its GSII variant, although Samsung says that all three models include an 8-megapixel camera, 2-megapixel FFC, 16GB of built-in storage, and Android 2.3 with TouchWiz 4.0. Availability details for the T-Mobile Galaxy S II are just as sparse as its spec list: T-Mo says that the device will launch sometime "this fall."

As expected, there was no mention of a device for Verizon. Those customers on Big Red shouldn't fret too much, though, as the rumor mill claims that Verizon may be getting a similarly specced device in the near future.

So there are your U.S. Galaxy S II variants. The European GSII has been regarded as one of the top Android phones on the market since its launch earlier this year, and it looks like the versions released here in the States could very well continue that trend. What do you all think of the trio now that they've finally been officially unveiled? If you're planning to pick one of them up, be sure to let us know which model will soon be calling your pocket home!

P.S. For those of you interested, we've also got the individual press releases for each of the GSII variants: AT&T, Sprint, T-Mobile.
