I have an iPhone 5 and I'm not happy with the way the white lightning usb cable integrates with the coral red interior. I purchased the Griffin Coiled USB-to-Lightning Cable and it integrates quite nicely.
I am also using a Monster iCable with a cigarette USB adapter for my wife to charge her 4s in the passenger or back seat.
I will sometimes leave the phone in the cupholder but usually tuck it beside the hand brake (when not in my pocket).
