Do you repair them first or sell as pictured?
First, you gotta collect the phones. This can be done by simple methods, such as getting busted for drunk in public and being assigned community service. Then you gotta get onto a good crew, because the crew boss might already have a hookup for selling smashed phones. Then you need to find somebody who wants smashed phones, hopefully one who has Jacobs chucks in trade. I prefer V-blocks and 1-2-3 blocks, buy your guy might have chuck jaws or even a Mr. Mister to trade...
