On the 2nd generation, the dock connector is solder to the board. Check on the guide [guide|1127] page 5 shows the dock connector. So you have to remove the logic board and then remove the dock connector by de-soldering it as well as the 2 prongs on the side that hold it on the logic board. Not a terrible job but it does require a steady hand, good eyes (or a magnifying lamp in my case)and good tools. Good luck and let us know how it is going.
