OK, so I don't even carry a cell phone but that does not mean that I don't pay attention.
It would seem that ALL current smart phones have an FM radio chip. It would also seem that the service providers refuse to activate this chip as they want you to pay to stream music.
There is an organization that is fighting this. If you are interested visit
http://freeradioonmyphone.org/Oh, from radio broadcasts here in Sheridan Wyoming, there is supposed to be a free app available to access this FM radio chip on this site but I sure cannot find it. Mayhaps you have to access the site from a smart phone to see the link to the app... I just do not know...
