If you want to make a stereo converter with a SE socket, you should use pins 5 and 6. It may not work well with an amplifier due to low output i.e. just enough power for headphones . (May need pre-amp).
To make a stereo-amp using the cell phone you must shortcircuit pins 8 and 9. Then connect the outputs (L) (R) (GND) using pins 5 = (left), 6 = (right) and 9 = (GND).
Sony-Erisson Walkman original handset uses pins 2 (GND), 5 (Left) and 6 (Right).

(*) For incoming call answering short pin 3 and 4
