hi! nice work so far! i wonder how the power management will handle this... usually (i.e. when charging via usb-board) the phone stops charging when the internal battery is full... be sure this also happens when charging via those connectors or you'll end up with some pretty expensive fireworks... also be sure you don't run into trouble when connecting the phone to a usb-port while this other half is attached (would be double-charging, wouldn't it?)
