Seth Weintraub, of 9 to 5 Mac, has received a tip that Apple is developing an FM Tuner application for the iPhone and iPod touch. The application is said to be able to run in the background, just like iPod.app, and will offer functionality similar to that in the new iPod nano.
The iPhone 3GS along with the second and third generation iPod touch have been able to receive FM radio signals but the feature has yet to be supported in software.
Weintraub’s source says that the hold up is due to the integration between the radio app and the iTunes Store. While listening to a song you would be able to tap a button that brought you to the song listed in iTunes, then you are just one tap away from purchasing the song.
Weintraub also mentions that the iPhone 3GS and current iPod touch supports 802.11n in hardware which could also be turned on in the future. But, I haven’t been able to confirm that the iPhone 3GS’ hardware supports such functionality. The only references I’ve found to the iPhone 3GS having support for 802.11n were in rumors before the devices launch.
