I used to enjoy listening to movie soundtracks on my iPod while on the move but I often turned off the screen to stop the battery running out. This was no problem with my iPod, which had a TV output mode that allowed me to get audio and put the screen on standby. There's no such function on my new iPhone.
Can you suggest a solution?

DQ: You're right. Unlike the iPod, Apple's iPhone does not have a special TV output mode. But one of my friends, who is a die-hard iPhone user in Hong Kong, has a solution.
The headset that comes with the iPhone has a tiny remote control hidden in the microphone bead. You squeeze it to accept and cancel phone calls but it also controls the music player side of the smartphone - one squeeze to pause a tune and two squeezes to jump to the next track.
This is what you need to do: start your movie then press the iPhone's power button. The display and audio will switch off. Now squeeze the controller once and the audio stream of the movie you were watching will play through the earphones.
I recently bought an iPhone on the grey market.
