I was editing my post when you were replying. Read the rest of my entry. Of course, you could be right in the aspect that the T-Bolt lens comes from Vietnam or china whereas the Evo Lens may have come from America or Taiwan. Regardless, just because it may have come from a different country doesn't mean it would be "improved" as it's spec'd the same. A lens either focuses, or it doesn't, therefore if the diameter of the lens is xx.x millimeters, they are ground to the same angle or they won't focus unless it is moved a significant amount further from the shutter/sensor. Seeing how the phones, for all intents and purposes are the same thickness, it would be the same lens. The CASE is thicker on the bolt to go flush with the camera lens, but that's so it doesn't scratch.
