I plug the iPhone into my car stereo and my speakers at work using a 1/4" cable in the headphone jack. The iPhone's jack is so deep-set that the plastic casing on my cords wouldn't fit in there, so I use a knife to cut away a bit of the plastic. Now I can fit the wire in there and it works just fine... is there any risk to the iPhone from doing this? Did they make the jack useless for standard plugs for a reason?
