ok, so the usb charger bit is quite funky, but, you know that those cables are just reverse wired standard video cables ? – like the ones you get for outputting form a MiniDV cam, you just need to swap the video and one of the stereo channels around and bingo.

ive always hated apples approach to cables, and £35 is prohibitively expensive, especially when you have the ability to lose cables that i do !
