A new breaking report from BGR indicates that the new superphone, the HTC One X will be launched on AT&T within a week. In case you have missed it, this phone is a pretty big deal... it's one of the most feature-packed and powerful devices to come along in a long time. The AT&T version will not come with the NVIDIA Tegra 3 chip because it doesn't play well with LTE; however, it won't be gimped in any way. They put the Snapdragon S4 dual-core Krait chip in, that in some cases is actually faster than the NVIDIA Tegra 3. Other than that, this version should be almost identical to the international version. This differs from Sprint's version, the HTC EVO 4G LTE, which actually received some additional specs and an aesthetic redesign on the outer shell.
