HTC announced their new flagship One X smartphone at the Mobile World Congress Feb. 26, and it will be on AT&T in two months or less. It will face off with the Samsung Galaxy S2 Skyrocket and Sony Xperia Ion as the best 4G AT&T phones, but the One X won't be a quad-core device like its international counterpart. That's because the Tegra 3 chip doesn't support AT&T's LTE network, but the 1.5 GHz dual-core Snapdragon S4 has performed well, and should receive a warm welcome from AT&T customers.

HTC also announced their One S and One V devices, with the One S coming to T-Mobile in the Spring. AT&T customers are about to get flooded with new devices, as Samsung recently released the huge 5.3-inch Galaxy Note, and Nokia is close to launching their Lumia 900. There's no word on HTC's pricing for the One X, but the Galaxy Note debuted at $300, AT&T's most expensive phone. That's likely where the One X will debut, but the Galaxy S2 Skyrocket is only $200, so customers will have a tough choice to make. Start the slideshow to see if HTC can take down Samsung in this smartphone battle. Let us know in the comments if you're thinking of joining AT&T for one of these phones, or if you're ready for your upgrade.
