Yeah, the iTrip se I have an iPod Touch and I have travelled 2 months through the USA in a rental, enjoying the tunes from my iPod using the iTrip The iTrip has a dock connector so you can attach it to the dock port of your iPod / iPhone, and it has a mini-USB port to charge your iPod/iPhone with a charger in your cigaret lighter. The thing has a digital tuner as well, works just fine
The iTrip is an FM transmitter made by Griffin Technology as a third party accessory for Apple Computer's popular iPod MP3 player. The iTrip plugs into the headphone socket of the iPod and converts the audio output into an FM radio signal, which can then be picked up by appliances such as car radios. Software bundled with the iTrip adds a playlist to iTunes containing audio files with a special set of tones in them. The iTrip Black is identical to the standard iTrip but black with white lettering, to match the design of the iPod U2 Special Edition.

I can confirm that the iTrips that plug into the dock connectors of iPods do indeed work with the iPhone. It gives you a pop-up saying "this accessory is not made for iPhone" but you can dismiss that and then the iTrip functions as normally.
