I'm using a cable and dock for that matter that came in a kit from Walmart.com. The whole kit is for an iPod Video it comes with a dock with remote, car charger, home charger, A/V cable, Audio cable and a few other random goodies. It works great and the whole kit was under $50.

The dock is for an iPod and since it's not an apple product the inserts wont work without major modification so if you're one of those people that freaks out because your iPhone is just balancing on the connector inside the dock then don't get it. I myself don't care. I use my iPhone on my iHome, my iLive studio come to think of it I don't even think I have an iPhone dock anymore?
