If you DON'T put it in airplane mode, you will hear interference with the music when emails are downloaded or if the phone rings. But if you DO put it in airplane mode, (of course) you won't be able to use the iPhone as a communication device. Because of these issues, I most of the time use my other iPod for music and leave the iPhone on my belt.
