[muglo] Re: iPhone FM Transmitter

Here's more info on the iPhone not supporting existing iPod charging  
devices:

Old chargers don't work with the iPhone 3G because it no longer  
supports charging via the Firewire pins (pin 19 and 30 on the dock  
connector), and can only be charged via USB (pins 16, 23, 25, and  
27). Virtually all car chargers charge via 12v firewire, except of  
course the ones with a built-in usb port. This is because the car's  
electrical system is already at 12v, so its cheaper to manufacture  
firewire-based chargers, instead of using voltage regulators to  
charge via USB (5v).

Currently, the only way to charge an iPhone 3G is through a charger  
that uses the USB pins, which unfortunately can only be found on a  
computer, wall charger, or some audio docks. Currently there is no  
"fix" (aside from tearing the cable apart and soldering an in-line  
voltage regulator), but apparently apple is coming out with some sort  
of adapter, because it looks like all iPod car chargers have this  
problem.

Also, here is an FM Transmitter that SUPPOSEDLY works with the iPhone:

As well, a slightly cheaper one that works, but with the iPhone  
switched to Airplane Mode:

"The following product will work with the iPhone, but with limited  
functionality, will only charge the iPhone. When the transmitter is  
connected, the iPhone will display a dialog box, that asks: would you  
like to turn on the Airline mode? Select Yes to assume functionality  
of the transmitter."
