I suppose this was a logical & inevitable move. Ring tones are a huge business everywhere else in the world, & the market is only just starting to pick up here in the U.S.

"Created in partnership with Dwango Wireless, the Napstertones service offers most ring-tone downloads for prices between $1.99 and $2.99. For now, the service is available to Cingular and T-Mobile subscribers, but the companies hope to make it more easily accessible through phone carriers' networks later this year."
