If you're looking for a simple, inexpensive case for your HTC ThunderBolt, the HTC Skin Case may be the way to go. It's a very basic rubber case and if you're used it on other phones, you'll be plenty familiar with it here.
It's a single piece of non-slip rubber that you fit the phone into. There are cutouts for the 3.5mm headphone jack, power button, camera, kickstand and microphone, so you don't lose any functionality there. It'll protect your phone from basic dings and scratches. And while there's no direct protection for the touchscreen, it will keep the screen from touching the surface when placed face-down.
Our only real ding on this case is its propensity for collecting dust and lint in a pocket, and that the case could be a little more snug. That said, it's easily removed, but doesn't feel like it could come off at any moment. And because it's rubber and you can remove it easily, you also can give it a light rinsing if need be.
We've got more pictures after the break. You can get the HTC ThunderBolt Skin Case is available in black, gray, blue or raspberry for $9.95 in the Android Central Store.
