I had a question about using the universal dock and charging the iPhone in the car. I have the universal dock set up in my car and I have an old car iPod charger (firewire based). The iPhone won't charge when the car adapter is plugged into the universal dock. So I think it's because it's an old car charger but before I go and buy a new car charger, I want to see if anyone has used the universal dock with a new car charger. Does it even work? Post if you have any experience with the universal dock and a car charger. Thanks!
