A new rumor this week suggests that Apple is developing an FM tuner app for iPhone and iPod touch users. Though not every device has the capability to receive FM signals, building the app is a simple way to add an extra feature to the iPhone 3G, iPhone 3GS, and second- and third-gen iPod touches.

An anonymous source for 9to5Mac says work on the app is mostly done at this point, and will likely take cues from the FM tuner interface of the recently introduced fifth-gen iPod nano. However, Apple is reportedly still working on integrating mobile iTunes Store purchasing into the app. This is an obvious extension to iPod nano's song tagging feature, which allows a user to tag songs they like for possible later purchase via iTunes. Integrating direct purchasing would increase the impulse purchase factor.
