ok. I have an iphone 3GS.
so the ipod cable you are talking about is the charge/itunes cable for in-home/computer use is what you are talking about that will charge the iphone4 in the car? Your apple AV cable will not charge in any situation, right?
I am going to just use the cable I received from Jeff, but if I sell the apple cable, I want to make sure I advertise it properly.
