I checked the continuity between pins 1/2, 11 and 29/30 on my 4G, and while 1/2 and 29/30 are connected, pin 11 (serial GND) isn't connected to the conventional GNDs of 1/2 and 29/30. I think it may be connected via whichever accessories may need it. Is that what we need to do? 310K isn't listed on the pinouts.ru site, and Google searches aren't really showing anything either. Very interesting.

Tie pin 1 & 2 together (1 = Ground, 2 = Audio Ground)
Tie 1 & 2 to 11 (Ground & Audio Ground plus Serial Ground)
Pin 3 = Right Audio
Pin 4 = Left Audio
Basically, as soon as you touch pin 1 to pin 11, the audio stops playing out of the on-board speaker and is routed to pin 2/3/4 as per normal LOD.
You DO get the "This accessory is not made to work with iPhone" message - Just press yes to turn airplane mode on, or no to continue.
Happy Happy Joy Joy!
Edit for clarity:
Pin 1 = Ground (Connect to Pin 11)
Pin 2 = Audio Ground
Pin 3 = Right Audio
Pin 4 = Left Audio
Pin 11 = Serial Ground (Connect to Pin 1)

Wait for the message
Press Yes or No (I press No)

Very interesting. Thanks for the work, MrJoshua. Now we just need to spread this over the interweb, since it seems like no one knows how to get a line out signal from the iPhone. And to make things clear, pins 1 and 2 are connected on the iPod board, so there isn't any need to solder then together in your connector. For that matter, you could just use pins 15 and 16 (both GND) since they're closer. Thanks for sharing.

Nice, should work.
Congrats MrJoshua
Perhaps a 1K from Pin 21 to ground we'll have it recognized as a real iPhone accessory.
Anybody have an iPhone dock that can measure resistance between pin 21 and ground?
I tried a 1k resistor between 21 and ground and it made no difference to the message that pops up.
(I've digged this BTW )

Yes, I can attest to the configuration working since I built my cable awhile back from that exact same link. As far as I know Ken never had it right to begin with since his configuration required the iPhone to be rebooted etc...Upon multiple requests for the pinout from various people here, he never did supply any info to help!
Pinouts for Dock connector:
Pin 2: GND
Pin 3: Right Channel Line Out
Pin 4: Left Channel Line Out
Pin 11 should have a 1K resistor between it and pin 21, and also a jumper wire from pin 11's end of the resistor to Pin 30 of the dock. I've been using this for awhile and it works fine.
