In theory, Apple already offers ringtones for iPhone. However, one needs to already own the music track from which you want to get a ringtone. You will then have to pay a second fee, to get the track switch into a ringtone. In practice, most customers are using the freeware and shareware allowing already to generate for free ringtones from your music library. Of course, Apple and owners rights are theoretically losing money. Things might change. According to CNET, Apple might have negotiated with Majors to sell ringtones ready for the iPhone, and potentially independently of music tracks. Most users will adopt this new offer only if it is attractively priced. Let's hope that Apple does not take this opportunity to lock the current systems allowing to have "home-made" ringtones.
