have had my iPhone 3GS for a while now and after a long period of listening to music on it, I was wondering if Apple had improved the sound quality for the 3GS? I have the old 1st generation iPod Touch, and when comparing the sound quality b/t the two, I found that the iPhone had much crisper audio quality with a somewhat wider sound stage than my iPod. Both are on the same firmware 3.1.2, and I compared both using the same songs/headphone.
