Thats almost certainly a lie or misinformation, the baseband and wifi chips of an iPhone do have that capability, they are basically software defined radios. Its just that the firmware of those chips might have deactivated that capability. [edited]Apple generally wants you to use their music streaming service not radio.[/edited] Do people genuinely believe if a head of marketing of a corporation tells them that they "care deeply about the safety of our users"?

But do the devices have adequate antenna for FM band? Especially the newer phones without traditional headphone connector (headphone wire cannot be used as antenna). AFAIK you cannot easily have effective FM antenna inside the device because FM wavelength is relatively long.

Genuine question, because I know little to nothing about SDR: Even with SDR, don't you need an antenna that fits the wavelength? WiFi and cellular frequencies are far from FM frequencies. And I think most other phones use the headphones as antenna, rather than inbuilt antennas.

  Yes, all phones with FM capability uses the headphone jack, usb connector or passive antenna adapters to get the FM signal in the first place. There would be some options for the latest iPhones aswell even without headphone jack. Using an SDR you can generally receive a very broad range of frequencies its only a matter of the antenna. You can even build them yourself, there some tutorials that use a Pringles chips container to make a wifi antenna.

FM bands ~(88 to 108 MHz) are very different than cellular bands ~(850 MHz - 1900 MHz). All radios have frequency limits, so sure they could add AM or FM radio but it physically does not exist in iPhone 5+ so they would need to manufacture it. Consider light and Radio are the same thing, but frequency is really important.
