If you need to ask you probably can't do it yourself ;-) Schematics and component layout are available, and shorting a cap shouldn't be too hard. The components are small, and not far from the headset coupling caps. See sheet 3 of the component layout under the bottom right corner of U3001. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
