Hi, I "inherited" a cable from my uncle! It has a "point" that enters the iPhone. From that "point", it has two cables. One is to get connected to a USB port, and the other one, is to get connected to fire wire. Does it do more than just than connect the iPhone/iPod to either a choice of the USB port or to the Fire Wire ?? Thank you in advance, kind regards, igmolinav : ) !!!
