Since I havent been able to find a confirmation that the iPlayer does not work on a 3DS in the internet, I tested it myself regardless of the consequences ("brick rumor", you know). When inserting the iPlayer the 3DS detects it as the game Fish Tycoon from Majesco Entertainment (which makes even the iPlayer illegal btw). Any attempt to launch the cart will result in a message, saying that this cart cannot be read. From this point the cart is not being detected anymore unless you eject and reinstert it. The cart itself became warm really quick. There are no traces of the cart in the activity log which leads to the conclusion, that only successfully launched titles are being recorded in the log. Thats all I intended to say. Cheers!
