My phone farm is very reliable but constant downloading, buffering, caching, memory swapping and playing video takes its toll. Every now and again I have to cull a phone and replace it. The culled phone I either sell or recycle. Today I sold such a phone for $5.00 at the local recycling kiosk, EcoATM.
Since I bought the phone, I’m counting the $5.00 as a rebate on the purchase price, and as such, as found money. This found money I’m investing in my Prosper account, which is currently returning 11.11% annually!
