Mod which file for custom EQ?

[denonade]

I think most of iPod users know this fact from n years ago. That is we can't sync the custom EQ made by itunes to iPod. And I found this happen to iphone as expected. For high-end ear/headphone user, we all love our own custom EQ for our own ear/headphone.

So, is there any way to mod the iphone to have our own custom EQ? I just think can we hex edit the preset file(where it is?) and override one of preset says "Flat" to be our custom EQ that made by itunes?

Please advise, thx a lot

nobody has any idea?
