There is a small amount of gold in an iPhone too. It is recovered during the recycling process. Silver is actually a better electrical conductor than gold. But silver oxidizes, so in circuits where the conductor has to have contact with the air, gold or copper is used.
ETA: If your car ever needs the catalytic converter replaced, make sure you tell the mechanic you want to keep it. I sold mine on eBay to a buyer who knew how to extract the platinum and other precious metals out of it.
