According to 9to5Mac, Apple [AAPL] is working on an FM radio App for the iPhone and iPod Touch, and apparently the FM radio application will be for current models of the iPhone and iPod Touch.
It looks like Apple will use the FM transmitter which is currently in the iPhone and iPod Touch, but isn’t used form Fm radio at the moment.
Apple’s iPods and iPhones have been able to receive FM radio signals for some time now. The latest generation of iPhone and iPod touch can even broadcast FM signal, for instance to a car stereo. The ability of the iPhone and iPod touch to receive FM signals has been used solely in the implementation of the Nike+ ecosystem to this point.
As usual this is just a rumor at the moment, so I guess we will just have to wait and see what Apple has up their sleeve for the iPhone.
