I doubt there are JTAG pins anywhere accessible on the board. I am wondering how they loaded the initial code to these devices, but I can't see any way to do this except before the chips where soldered to the boards. There is simply nothing on this board you cold make a quick connection to except the dock port, but I doubt that JTAG is in there somewhere. That JTAG finder just helps to get the pinout if you have a dozen touchpoints on the board. Whe have the exact opposite problem: Nothing to hook up to. (Well, at least nothing I can see on the various PCB scans, I didn't get my fingers on a dissected iPod yet.)
