Has this been mentioned on here before? Don't remember noticing it. (I've no connection to whoever these people are, not shilling this, or particularly recommending it, honest! Just noticed someone selling an ipod with it on Ebay, and was intrigued by the custom back-plate as much as anything - I'm not actually interested in bluetooth myself, can't be bothered with wireless, but had thought for a while there was milage in more aftermarket mods for the ipod, including a better/larger housing, and thought this at least _looks_ pretty cool, aesthetically-speaking)

(What I _would_ find really useful would be a means of synching with USB-C speeds, but I presume that's beyond what a simple mod could do - that the above adds a USB-C port I presume doesn't actually change the speed of data transfer, just the plug type).
