What's the latest way to turn a quick buck? Try turning over your old mobile phone to an ecoATM, a machine that scans devices ranging from phones to MP3 players to determine their worth and then pays consumers cash for them. Compensation ranges from just a few dollars to more than $200 depending on the device. The San Diego-based ecoATM company resells or recycles the gadgets it receives.
