HTC kick-started the world’s largest mobile tech trade show, the Mobile World Congress (MWC), by launching its very first quad-core smartphone: the HTC One X. The device will run on Android 4.0 Ice Cream Sandwich and features 32GB internal storage, quad-core processor and a huge HD screen.

It all sounds too good to be true, and for some parts of the world it is. The quad-core processor is only for the global version, while the U.S. version, bound for AT&T within the next 60 days, will have LTE capabilities and a dual-core processor.

The global version of the HTC One X will boast Nvidia’s quad-core Tegra 3 processor. According to HTC, however, the chip was not LTE compatible at the time of the production, several months ago. The LTE will be available though for future quad-core phones with Tegra 3.

For now, AT&T’s version of the HTC One X will use Qualcomm’s dual-core Snapdragon S4 processor, trading processing power for better network speed. Both AT&T and HTC are confident that 4G LTE weighs more than four cores in the highly competitive U.S. market. Other features of the ONE X include 32GB internal storage, a huge Super LCD 2 display of 4.7-inch 1280 x 720-pixel resolution and a single 8-megapixel rear-facing camera.

HTC notes that the Super LCD 2 display sports better viewing angles and less glare than the Super LCD technology it used in the HTC Rezound. In addition to the 32GB of internal memory, the One X also has 1GB of RAM, free Dropbox storage and new imaging and audio features. Sense 4, the latest HTC UI, will run ImageSense, adding software to improve the phone’s camera, while Beats Audio will be built into the device.
