All I can say is every single GSM phone I have ever seen -- every single one -- affects speakers like that, so if it could have been done I bet they would have done it by now. I could be wrong, but if it's fixable then I think it would have been taken care of a long time ago. I think it's more likely the speakers' fault for not being well shielded, because it seems to happen more when I'm around cheap speakers than nice ones.
