"The unprecedented popularity of using hit song clips as ringtones has demonstrated the desire by T-Mobile's subscribers to personalize their phones with content that is in-tune with their lives," said Michael Butler, Chief Marketing Officer, T-Mobile USA. "Ringback tones are the next evolution in personalizing wireless communication through music and audio. With the introduction of CallerTunes, we're introducing yet another fun and innovative way for our customers to use music and other audio as a way to represent their style to friends and family."

T-Mobile has partnered with the three largest music companies -- SONY BMG Music Entertainment, Universal Music Group and Warner Music Group -- as well as key independent record labels and other content providers, to give subscribers the power to express themselves through the broadest collection of exciting ringback tone content to date. From platinum-selling favorites Barenaked Ladies, Beyonce, Disturbed, Simple Plan, Marvin Gaye, and Lil Jon & The East Side Boyz; to rockers, The Killers and 3 Doors Down; and classic artists Santana and Eric Clapton, T-Mobile's editorial team has culled the best content from a master catalog of more than 10,000 tracks.

As part of a CallerTunes 30-day free trial offer, T-Mobile and Sony BMG's J Records have partnered to make "Karma" by Alicia Keys the service's first Bonus CallerTune. For a limited period of time, subscribers to CallerTunes will be able to use free-of-charge a song clip from her multi-platinum, award-winning album, "The Diary of Alicia Keys".

"This service enables consumers to further personalize their mobile experience, while at the same time establishing an even stronger connection with the artists and music they love," commented Thomas Hesse, President, Global Digital Business, SONY BMG Music Entertainment. "We're delighted to be able to help launch CallerTunes with a great song from one of the most important artists in the world today -- Alicia Keys' "Karma" -- and we look forward to working with T-Mobile on the nationwide roll out of this new service."

Alicia Keys is one of the most nominated artists for this year's Grammy Awards with eight nominations including Album of the Year ("Diary of Alicia Keys"), Song of the Year ("If I Ain't Got You"), Best R&B Song ("You Don't Know My Name"), Best R&B Song ("My Boo"), Best R&B Album ("Diary of Alicia Keys"), Best Female R&B Vocal Performance ("If I Ain't Got You"), Best R&B Performance Duo or Group with Vocal ("Diary" with Tony, Toni, Tone), Best R&B Performance Duo or Group with Vocal ("My Boo" with Usher). She previously received seven Grammy nominations for her debut "Songs in A-Minor."

Users can represent their style through CallerTunes in a number of ways, including:

--Choosing your favorite audio clips from hundreds of original artist recordings. Users will be able to assign up to eight different audio clips for their friends and other callers to hear.

--Assigning individual audio clips to be heard by a specific caller, or groups of callers. For example, you may choose Marvin Gaye's "Sexual Healing" to play for that special someone when he or she calls.

--Specifying audio clips for a specific day, or during a time of day. For example, select Simple Plan's "Welcome to My Life" to play when you're cutting loose after work or school.

--Since CallerTunes easily can be managed through a T-Mobile phone or on the Web, changing your CallerTunes to reflect your current mood. For instance, selecting Sheryl Crow's version of "First Cut Is The Deepest" when you're feeling bittersweet!
