Despite being Sprint's version of the HTC One X, Bill Detwiler's teardown of the Evo 4G LTE reveals several important differences.
Sprint won't have a working LTE network in the U.S. until mid-2012. Even then, they will only offer LTE service in select cities. But, this fact hasn't stopped the company from releasing an LTE phone. And now that the HTC Evo 4G LTE has cleared U.S. customs, we can crack it open and compare the latest Evo to its cousin, the HTC One X.
Our Evo 4G LTE test unit had a 1.5GHz dual-core Qualcomm Snapdragon S4 processor, 1GB of RAM, 16GB of onboard storage (expandable via the microSD slot), a 4.7" Super LCD 2 screen (1280 x 720 resolution), an 8-megapixel rear-facing camera, and a 1.3-megapixel front-facing camera. It measured 5.31" (H) x 2.72" (W) x 0.35" (D) and weighed 4.73 ounces.

The Evo 4G LTE and One X share many components, such as the processor, storage module, and touchscreen controller. But, there are important differences—beyond the Evo's kickstand and two-tone case.
- Two-piece back cover: The One X has a single-piece back cover. In contrast, the Evo's back cover has two sections. The top half can be removed by the user to access the phone's microSD card slot. The bottom half covers the battery and is not designed to be removed by the user.
- Larger battery: The Evo 4G LTE has a 2,000mAh battery, compared to the 1,800mAh power unit in the One X. The Evo's battery is also easier to replace, as its connector is mounted to the top of the motherboard.
- microSD instead of microSIM: The Evo's motherboard has a microSD card slot instead of the microSIM slot found on the One X. Also, most connectors are mounted to the top of the Evo's motherboard. This makes working on the Evo easier than working on the One X.
- Internal construction differences: The Evo's vibration motor is mounted at the top of the phone instead of the bottom. The lower speaker is mounted to the front panel assembly instead of the back cover. And, the Evo lacks the separate circuit board that houses the One X's docking connector.
- Nearly identical cameras: Although I haven't tried to swap them out (yet), the cameras on the Evo and One X look almost identical.
As of this tapping, the Evo 4G LTE has an MSRP of $199 (with a two-year Sprint contract). And like the One X, it's a solid phone—even though the U.S. version lacks a quad-core processor. As CNET's Brian Bennett wrote, the new Evo is a phone "that's light-years better than its predecessors and flaunts enough features plus a delectable design to strike real fear in the hearts of competitors Samsung and Motorola".
