I have followed the instructions, got into dfu quite easily and followed through system/hardware/device manager/apple mobile usb driver and details. There was no option in widows (XP) for \"device instance path\" in the drop dowm menu. Can anybody suggest why not

Here\'s a stupid question. Assume I have got into dfu mode and have got my bootrom, how do I get out of dfu mode do I just disconnect the phone from the pc and restart it.
