Shortly after the announcement from HTC CEO Peter Chou at Mobile World Congress that AT&T would be a launch partner for the new One X, the US's number two carrier let fly a press release confirming the statement. What's there to take from it? Not much.
The primary differentiating features of AT&T's version will be a dual-core Snapdragon S4 (as opposed to quad-core Tegra 3) processor, as well as LTE connectivity. If you're wondering why AT&T is getting stuck with half the cores of the international GSM version of the device, you can look to LTE as the culprit. Basically, NVIDIA's Tegra 3 processor doesn't have any currently available radio configurations that will support LTE (though it will in the future), while Qualcomm and Texas Instruments have been the go-to choices for devices utilizing the new network technology.
