Hey guys,

Does anyone know if its possible to generate a radio frequency on iPhone? Is it possible to make a RF transmitter App?

Thanks,
Rick

No, it is not. You have no access to the radio outside of the high level APIs for launching a phone call and making a network request.

Probably. Depends on what type of RF you're talking about. It's an electronic device that will emit some form of RF during it's normal operation. You'll probably find that just dimming the screen display backlight will change a frequency being given off somewhere. Sticking the processor in an intensive for-loop will probably do the same. If you know how to read those frequencies, you have a programmable RF transmitter!

Is it possible to make a RF transmitter App?

Assuming you mean FM, then here's how I'd do it:
1. Find a bluetooth enabled device you can send your audio stream to.
2. Have that device output the analog version of the audio to a headphone jack, which in turn is plugged into a standard FM transmitter like you use in a car.
