Sorry, my ipod sent the message Too soon. Anyways, perhaps JTag halting has been disabled on non-dev models. I know on AVRs there are lock bits that can be set to disable reading/writing to the chip. Maybe the 8700 has something similar for jtag. Will look at the datasheet later. I wonder if other models have jtag on the same dock pins. I might be able to test my 4g if i can build a jtag unit and get a dock breakout. It makes me suspicious that apple would leave a working jtag lawing around, especially on the dock connector. Surely it would be disabled or something.
