What we have here appears to be some variation of the Samsung Galaxy S II, with support for 850MHz and 1900MHz GSM frequencies, making its way through the FCC. Now, we know what you're thinking, "didn't we already see an AT&T ready S II?" Yep, but this one sports a different model number -- GT-I9103, and you know where we've seen that before? Those mysterious Tegra 2-equipped Galaxy S II benchmarks. The rumblings of Sammy's flagship handset coming in two versions, one rocking NVIDIA's mobile chip, aren't without precedent -- Exynos is still fairly young silicon and this could be a way to boost supplies (as we put it, in the most politically correct terms possible) "outside its critical markets." In other words, don't expect to pick one of these up at your local AT&T shop, unless your local store happens to be in St. Petersburg Russia.
