Cables compatible with Touchstone? Hi All -- So I was looking at the high-output Seido wall adapter in the EverythingPre store but have doubts that it would work with my Touchstone. I got a wall charger from the local store (generic) and while it charges the Pre well in a direct connection, it doesn't charge at all with the Touchstone. Just an intermittent charge. :embarassed: So are there specific cables only compatible with the Touchstone? Or should I just have a Palm cable for my second touchstone and use the travel charger I got for just that -- travel. Any thoughts?
