I was watching the 20 minute 'tutorial' and noticed something during the presentation of contact. As you can see there is an area in the contact updating process that allows you to assign a specific ringtone for that person (a common ability in many mobile phones, I know) and I'm wondering if you might be able to use that area of iphone to assign mp3 itunes songs to a particular caller.
Just a thought, no response necessary I suppose.
