Galaxy S III AT&T and T-Mobile US versions confirmed

Bluetooth SIG approval pages have confirmed the existence and model numbers of the AT&T and T-Mobile US versions of the Samsung Galaxy S III.

The AT&T model number is SGH-I747 and should be based on the Snapdragon S4 chipset with a dual-core Krait CPU instead of the Cortex-A9 found on the international version. The reason for the switch is once again the lack of native LTE support on the Exynos 4 Quad.

Samsung Galaxy S III US-bound models

The T-Mobile-bound Galaxy S III version will be called SGH-T999, but its unclear what chipset will reside inside its body.

Never mind the photos, both devices will look different from the international version for sure and will will almost certainly replace the one-regular-and-two touch-buttons combo with four capacitive keys. There's also a good chance that one (or even both) of them will have 2GB RAM as the Japanese version.

The US release of the Galaxy S III is coming next month, so we should know more about the two devices soon.
