hey guys.. i also orderd a pixi back and touchstone (for $10) and was going to do the original mod shown in the first post but i thought after doing it i would still be able to use my usb to charge as well.. is that not the case??
If someone figues out the pin outs for the battery im wiling to risk the insurance cost to try this out..
I remeber that touchston charging was slower than direct usb charging so the option to quick charge with usb is critical IMO
