There’s an FM radio hidden inside of most smartphones, even though most phones in the US don’t actually allow you to use it. But soon, they may start working if you’re on AT&T. AT&T is starting to ask phone manufacturers to turn on the FM radios inside of their phones. A person familiar with the matter tells The Verge that AT&T isn’t making radio activation a requirement, despite what some news releases are saying. Still, it could have a big impact: for the most part, FM receivers seem to be turned off because carriers want it that way. Now that AT&T wants them turned on, there’s a decent chance of that happening.
