Rumor: Apple Unlocking iPhone and iPod Touch's Latent FM Powers
With Radio AppS  9to5Mac hears that the iPhone and iPod touch
are getting a radio app like the nano's that'll be able play FM
radio in the background. It'll be integrated with the iTunes
store, supposedly, so you can buy songs you like.  The hardware
capability for FM radio does exists in some models—the current
iPod touch and iPhone 3GS have FM transmitters, and the 2nd-gen
iPod touch also has a chip that's capable of receiving FM
signals, though it uses it for Nike+ stuff (so if there is a
radio app, maybe it'll just be for current-gen models).  It'd
make sense to add more software parity across the line, but who
knows—no date given for when we might actually see this FM radio
app. [9to5Mac}
