According to newly leaked information, the HTC One X could go on sale at AT&T as early as this week. This goes against previous information that suggested a release might be more likely in May, but the anonymous source of this new information is claimed to be reliable.
Apparently, AT&T employees have already started receiving training for the device, and availability details could be released tomorrow. The actual release of the One X would then take place within five to seven days.
Since the One X is compatible with AT&T's fledgling LTE network, it sports a dual-core Snapdragon processor that is just as capable as the quad-core Tegra 3 processor in the international version of the device. Other than this, though, AT&T's model should be identical to the international one.
In any case, you can expect full coverage of the One X's release here on Pocketables, including an exclusive unboxing and hands-on review.
