None of the firmware updates which Canon have released have addressed the problem of high ISO noise.

The reason being.....there isn't a problem, thus nothing to fix.

Im really surprised the place you bought it from didn't take the camera back for exchange. I had mine for about a month, made a call and told them I wasn't happy with the high noise levels (They knew about the issues on some of the cameras) and exchanged it, no questions asked. It was 2 weeks after the return period expired.
