Hey everyone! Happy new iphone4 user here! I'm wondering if someone could point me in the direction of something that charges your iphone in the car, and also has a FM transmitter. Does something like that exist? So basically, the car would be running the FM transmitter and charging the iphone at once. I ebayed for a bit and found this: http://tinyurl.com/2394cft but i'm not sure if it works as I intend it to. BTW, is it possible to play music via the sync slot in the bottom of the phone, or will I have to plug one part of the charger into the sync slot (to charge the phone) and one cable in the headphone port (to send the music to the transmitter). I'm hoping just one cable to the sync slot can charge + play the music, but i'm not sure.
