The HTC Evo Shift 4G makes a showing on Walmart site’s, and with the occasion we find out for sure that it will be running Android 2.2, while its screen is smaller than the Evo 4G’s, with 3.7 inches instead of 4.3, and a five megapixel camera that stacks poorly against the Evo 4G’s comparatively high end eight.

But the WiMAX enabled slider will get a processor upgrade, to a 800MHz Snapdragon identical to the one found on T-Mobile’s G2. Matching the upgrade is a downgrade in the form of a missing front camera.

Shipping is planned for January 9th, and a Radio Shack flyer pits the price at $150 with a plan.
