The iPhone's iPod:
After you transfer songs you can listen to them through the iPod
software, also installed on the device. Arrangement depends on
the way songs are set on iTunes, since you can't organize them
through your iPhone.
When playing a song there is two modes of display
1.    Horizontally
2.    Vertically
·         The horizontal display gives you a way to slide through
          your albums and songs but don't have any control buttons.
·         The vertical display gives you control buttons and on the
          top right you can find a toggle menu that flips to two
          different views one is the song that is currently being
          played while the other view is your list of songs.
iPhone's iPod Volume
If you are looking for a button to change the volume - You will
not find it. The Volume buttons are physical buttons, located on
the left side of the device. You can also control the iPod volume
while in the vertical display by sliding the slide button left and
right.
