HTC stands for High Tech Computer, which is the corporation name; located in Taiwan.

 

HTC has factories in Taiwan and Brazil. My bet is that the EVO was made in Taiwan, due to the advanced nature of the device.

Check out this video of the HTC plant in Taiwan making the Google Nexus 1:

Yea, then all you'd have to do is stick them in the dirt and keep them watered. After 90 days just pull 'em off the bush.

That way your $199 cellphone would cost your around $800.
