I really like Griffin’s iPod accessories, mostly because I think they have the best hackers. The new iPod nano iTrip looks like an excellent piece of engineering, but if you look close at the screen they’re not only use the FM add-on in dock mode (screen says disconnect) – the image which is normally a blinking O with a line through it is replaced with a Griffin logo. Digging in the firmware you find these things, but they’re doing this via the dock connector. Nice hack. I hope to take one apart soon. [via] Link.
