dont forget the gold on the batteries where they connect to the phone. It is easy to remove the board from the batery and strips nicely in AP to get the gold foils off. Of course, safely dispose of/recycle the batteries when done 8)
yes i agree the cell phones do have some very nice gold in them.
my suggestion would be to go to a recycling place and buy them
i've seen sevarl places on the web who sells them . i dont know how much but it would be worth at least looking into
