Owners of Apple's iPhone have long had the ability to create custom-made ringtones for their devices. The new music snippets are mainly a convenience, as they make it possible for iPhone owners to obtain a pre-cut ringtone instead of having to create their own.
Apple will announce the ringtones on September 9, the day the company has scheduled a press event, if managers can get them ready in time to sell, the sources said. An Apple spokesman declined to comment.
