Refurbished by the mobile phone company? That doesn't occur.

The used market for iPhones on Craigslist is actual users. The market is very strong, and so is the resale value of iPhones. There is one (1) explanation for this: iPhones hold their value better because they are more useful for a longer time.

As an aside, iPhones also remain able to run the latest version of iOS for roughly TWICE as long as Android phones.

There is no competition, here.
