  The HTC One X, HTC One S, and HTC One V. All three smartphones were unveiled at the Mobile World Congress Monday, Feb. 27, 2012 in Barcelona, Spain.

The Mobile World Congress, an event traditionally centered around the latest mobile technology of the age, revealed many new gadgets, including a slew of smartphones for HTC and other companies that look fairly impressive.

The first day of the Barcelona-based tech event was dominated by Android, and underscored by HTC's unveiling of their three new smartphones: the HTC One X, HTC One S, and HTC One V.

All three of HTC's newest phones offered the much-sought-after Android 4.0 Ice Cream Sandwich operating system. But that's pretty much where the similarities end, as HTC seems to be marketing each phone to a different demographic.

The HTC One X has a powerful Tegra 3 quad-core processor, a 4.7-inch Super LCD display with 1280 x 720 pixels, and an 8-megapixel camera that includes an ImageChip that kicks up picture processing - the camera is fast enough to take pictures every 0.7 seconds.

In addition, it comes with 4G LTE capabilities, Beats Audio software, and a polycarbonate shell. When shipped to the U.S., though, the phone's Tegra 3 processor will be replaced with a SnapDragon S4 processor instead. It is set to debut on AT&T's network in April.

HTC's next phone, the One S, is a slightly pared down version of the HTC One X, but for T-Mobile's HSPA+ network. A 4.3-inch resolution with 960 x 540 pixilation and a dual-core SnapDragon S4 processor are a little less quality than it's big brother, the HTC One X, but the camera and software are the same.

Finally is the HTC One V, which will most likely be the least expensive of the company's new smartphones. It has a 3.7-inch display with 800 x 400 pixiliation, a 5-megapixel camera, a 1GHz SnapDragon processor, but comes with Ice Cream Sandwich as a standard.

In addition to HTC's smartphone unveiling were demonstrations by Sony, who showed the Xperia P and Xperia U - neither with the all-important Android 4.0, reduced to Android 2.3 Gingerbread instead - and the Samsung Galaxy Beam, whose main draw is the ability to project a 50-inch, 720-p picture on any surface.
