Fairphone is a group in Europe committed to the responsible manufacture of smart phones. From their website (www.fairphone.com):
This quality smartphone lets us open up processes and start a conversation about what is truly fair. From conflict-free minerals to fair factory wages, we’re making improvements one step at a time. Your purchase supports better ways of doing business that aim to inspire the entire industry.
Right now they only sell and ship inside Europe. If they eventually make a Sprint-compatible phone, I think Ting should embrace it whole-heatedly.In fact, I think TIng and Fairphone are such a good match that you reach out to Fairphone and offer to help them into the US market. Just make sure I'm customer #1.
