What i like to do with my old electronics is strip them for parts. Just start disassembling it, taking every thing off of it that seems like useful parts. Having a sodering iron and some sprig helps. Look up the ID numbers on the items you've salvaged to get pin-outs and data sheets. I really dont know if this would work for phones though since they use all that surface mount technology crap and youd probably need one of those tiny ass sodering irons. You could try to reprogram the EEPROM in it. Or you could get $5 for em and sell them to gizmo or even better 'donate' them to UGN Security.
