Get the TuneIn Radio app. It basically gives you access to most every major FM station around the USA... No reception issues, as long as you have your 3G/4G signal. Makes an FM radio obsolete for me. Give it a try.
and if your favorite station isn't on Tune In theres a pretty good chance its on iheartradio.
I never understood why someone would want the FM tuner with the possible exception of preserving data usage but its unlimited on Sprint.
If its that important to you, you can purchase a memory card with NFC built in. Viola, fix!
