9 to 5 Mac is reporting that Apple could be looking to add FM radio support to the iPod touch and iPhone via an app. The story which is fuelled by a tip submitted to the rumour site suggests that the app from Apple will be allowed to run in the background and will work in a similar way to the new iPod nano.
9 to 5 Mac states that the project has been delayed while Apple works out how to implement the iTunes Store to allow easy purchasing of songs being played on the radio. Additionally all iPods and iPhones are said to already have hardware capable of receiving FM signals.
