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.
