No, the problem is that you can't get decent AM reception with the
sort of RF that's flying about inside a cell phone, putting in the
necessary shielding would make the phone much larger and heavier, and
in any case there's nowhere to put a proper antenna.  You could put a
receiver chip in, but the results would inevitably be unsatisfactory,
and the manufacturers feel (rightly) that the complaints would cost
more than they could possibly gain from the (nonexistent) market for
cell phones with built-in AM radios.
