Please forgive my ignorance of terms--the 3G is my first gadget from Apple besides our Mac Pro. (My husband has a 3rd gen ipod, but I have always been a radio listener.) Question: I want to listen to the music on my phone in the car while charging at the same time. Is there an all in one car charger that will do this so it is plugged in the bottom, not in the headphone jack/aux in? I don't want a separate iTrip and the charger...too many cords. I want it all in one. Does that make sense? if so, what is it? How much? The store says they have them in stock, but I don't see it online and I really don't want to drag my two small children with me there if it isn't what I really want. THANKS!!!
