Source: Article originally from: The first thing we thought of, was making the T-Mobile G1 send the audio to an i Pod Speaker set we have.
There is a sea of i Pod accessories, so naturally the dock connector has a well known pinout.
Figuring out the pinout for the HTC Ext USB connector wasn’t too hard, I just split open my hands free adapter I got with my T-Mobile Dash. It took a bit of fiddling to discover that connecting pin 7 to the audio ground ( pin 8 ) turns on the external audio.
Sparkfun sells 30 awg (Gauge) wire wrap wire that is perfect for soldering to the ultra tiny pins on both the HTC Ext USB connector and the i Pod Female connector.
Update -T-Mobiles official word on the matter: While I understand that many of you have downloaded this update and seem to have it working, T-Mobile cannot support you in doing so.
If you download and attempt to install this or any other update (regardless whether its from Google or not) to your device, and it is rendered unusable, you are out of luck.
We used pins 1, 2, 3, 4, 16, and 23 on the i Pod Female connector.
If you gently bend the pins out it makes it much easier to solder, but be careful the pins break easy.
