Diy Ipod Line Out Dock Pinout

The Definitive Answer to the common Question:  "What is the Pin-out for a Line Out Dock for my Ipod Generation X?"  The answer is very suscinctly described - with pictures here.  This apparently works with G3 Iphones and is compatible with prior versions of the Ipod Classic and Nano.  Credit goes to forum user Good Times http://www.head-fi.org/user/good+times .  His post is in the following thread and is reproduced below:

I've just finished this and tested this on the iPhone 3G, iPod Touch 2G, iPod Nano and 3rd Gen iPod. Works flawlessly on all. No messages on iPhone or iPod Touch. I used a single 68kohm resistor just to make it easy. 

I think everyone can now consider this the universal solution, thank you all for your advice/input.

PS joining pin 11 and 15 can simply be done by bending the pin legs. Easier than soldering an extra jumper wire. Also, my question (re echo) a few posts up was answered by the fact that after re-inerting pins 2-4 after soldering, they had come out slightly just before gluing. I recommend not pulling them out, just soldering whilst they're in.

hi bro, wat is the function of a resistor there for ? reducing noise?
does it affect sound quality since no resistor added ? im wondering how i can add a mic line in through that, im using ipod touch G1
khanhhoa1912: the resistor is for the accessory indicator/serial enable/ it is a 68 Kohms which makes the iPhone 3G send the audio through the line-out without any messages. This way the plug is compatible with many Apple devices.
@musivheaven, so do you have to use a resistor when making an LOD for an iPod Classic?
@Dutch-Guy: No, you can ommit the resistor for the iPod Classic.
@musicheaven: Nice! Would it than also be possible to connect all the other pins to a female ipod connector so I could put it in a dock and connect a cable to it to charge my iPod or transfer files?
I would like to put the Black Gate capacitors here. Can you help me what goes where?
