GT-i9100, colloquially known as the Galaxy S II? Sammy's been tight-lipped about which US cellular carriers might offer it, but the Federal Communications Commission might have an idea. You see, the Exynos 4210-toting Super AMOLED Plus smartphone just made its way to the FCC authorization database, 850MHz and 1900MHz GSM frequencies in tow -- which just so happen to be the ones required to get a gig at AT&T. Mind you, the handset could also be moonlighting in Canada with those particular bands, but the odds are decent we'll see it stateside sooner than that. By the by, this particular Galaxy S II is also sporting 2.4GHz and 5GHz frequencies, meaning it'll almost certainly come with dual-band 802.11 a/b/g/n WiFi.
The Galaxy S II wasn't the only Samsung to hit the FCC this week, though, as the SGH-i708 also dropped on by -- it appears to be a worldphone with 850 / 1900MHz GSM frequencies alongside CDMA, EV-DO, and the standard Bluetooth and 2.4GHz WiFi.
