Okay, almost all the messages here about modding/rooting the PDN say that I should have a factory copy of firmware to burn in case of trouble. And not to try these things without at least being familiar with the firmware burning process.Well, my new PDN has newer firmware than what is shown on the PD website! So if I lose my firmware, I have nothing to backup to... right? Does this mean that I have to wait for newer firmware to be posted on the PD website? I guess it does...Bummer!
