Sprint, which launched the first U.S. mobile music store in October, has reached one million mobile music sales. Songs are $2.50 each and downloaded over the carrier's wireless network direct to the cell phone. Subscribers must have a compatible phone and take the Sprint Power Vision multimedia service at $15 per month.

Sprint seeks to capitalize on the popularity of ringtones with the full length music downloads. The Sprint Music Store was launched with a large advertising campaign, including the Super Bowl and Grammy Awards.

The one million sales mark indicates initial success. It remains to be seen if it's just a fad or a sustainable revenue source. Sales need to be much larger to be worthwhile for the large mobile carrier. Verizon is expected to announce a competitive service soon.

More information on the service from the press release follows:
