I'm curious: why is the focus so squarely on Apple? Apple seems to be one of the few phone manufacturers that has a Code of Conduct for its suppliers, that audits those suppliers, and that reports on the results.

Every one of the Top 10 phone manufacturers uses FoxConn to do assembly, not just Apple. Apple — as we seem to be continually reminded when the subject isn't "ethics in smart phones" — is a minority vendor worldwide.

Are the 75% of the smart phone market consisting of Android phones (and thus, not manufactured by Apple) issue free? Are the even larger number of lower-end phones (also not manufactured by Apple) problem-free somehow?

I wish that Apple would bring its manufacturing back to the US, myself. That would solve any ethical problems, but FoxConn would still be there, not treating its workers a bit better.
