I realize that this was posted a while ago, but for those of you who come across it, it really works.

What I used (and works):

█ iPhone 8GB Unlocked using 1.1.1
█ Nokia BH-503
█ Also working with 1.0.2

Method:

1. Pair your headset, make a test call to see if it works. End the call normally.
2. Dial *#307#, press call.
3. Press the answer button twice with 2 seconds delay in your [COLOR=#FF7F00 ! important][COLOR=#FF7F00 ! important]bluetooth[/COLOR][/COLOR] headset (If you don't do this correctly, you will continue to listen the ringtone in headset)
4. Press answer on iPhone.
5. Press the home button, do NOT end the call.
6. Open [COLOR=#FF7F00 ! important][COLOR=#FF7F00 ! important]iPod[/COLOR][/COLOR] and play a song, you won't get sound from iPhone, nor headset.
7. Once it is playing, press the home button.
8. Open phone.
9. Dial 0, press Call.
10. It will ring again, answer.
11. Press audio source, select your headset.
12. Press home button, do NOT end call. (we're almost there)
13. Open iPod and play anything you like.

Shorter Way:

1. *#307# Dial, press the bluetooth headset button twice.
2. Answer on iPhone, press source.
3. Select bluetooth headset.
4. Press home button, open [COLOR=#FF7F00 ! important][COLOR=#FF7F00 ! important]iPod[/COLOR][/COLOR], play anything.

Now, you will get iPod playing through your bluetooth headset.

Cons:
- Cannot receive calls

I cannot take credit for this. I am currently using it, but here is the original thread:

Good luck!
