A while ago I seem to remember seeing an article in a computer mag about jury rigging a micro usb and 3.5mm audio jack to an ipod cable so it could be used with an ipod/iphone dock. Can't remember the publication but would like to get hold of it as i've been given a set of speakers and would like to use them with my sony erricsson xperia arc. If I remember correctly the jack was for audio and the usb was for power from the dock only. Did I dream this up or can it be done. Had a quick search of the net but can't seem to find anything relevant. I've seen cables for sale but this was a dirt cheap alternative. Cheers.
