For anyone trying to compare and argue the sound of iphone 3gs and 4, I found this great article. They did a good measurements on 3gs, 4 and Samsung Galaxy S as well as subject statements on their sound signature. If you browse their website, you will also find review on 3gs and 4 separately. I hope this is no duplicated effort. :)
