Price of the Freerunner spare parts

Thanks, At one point I suggested that an ingenious person might change this
particular resistor check so that other chargers would work in fast mode (
if they were capable) I can't recall where that discussion ended up.
So for example, My moto mini usb is 850ma, So I would just turn off the
software resistor check plug it into my moto charger and ?? not blow it
The open source aspect of this, of course creates opportunities and dangers.
lets keep the discussion going. My goal is not to turn Openmoko into a
supplier of expensive chargers. We would rather leverage what is already out
there. my moto charger was outrageous; I got the Igo for free a long while
back when they first started, so hey cant beat that.
your thoughts, always appreciated

Correct, it checks for 48k-OHM resistor on ID-pin of mini-USB, then enables
instead of 100/500mA USB-standard.
You also may enable 1A-mode (and 500mA mode) via some small GUI-app IIRC.
