Does anyone know how the volume of the music, played from the iPod app on the iPhone, compares to that of the iPod nano? POP email and audio volume for music are my two prime considerations, and since it appears I can get POP email, I'm only concerned now about the volume. I see lot's of folks contend that the speakerphone volume is not great, but I don't care about that for the most part. I want LOUD rock-n-roll, though, when I use the iPod app.
