Exclusive ringtones available under UMG deal.

Virgin Mobile USA and Universal Music Group are rolling out their second "First Dibs" mobile music deal, this time with exclusive master ringtones from G-Unit's Lloyd Banks and Young Buck.

The exclusives are timed to coincide with the release of Young Buck's new album, “Straight Outta Cashville,” as well as the popularity of Banks' platinum-selling “The Hunger for More From Banks.” Both sets are on G-Unit/Interscope. The ringtones are available as exclusives for the next three months.

"Working with UMG has given us the ability to serve up exclusive ringtones from a talented roster of artists that our customers know and love,” said Howard Handler, chief marketing officer of Virgin Mobile, in a statement.

The first “First Dibs” deal, which debuted in June, featured ringtones from D12.
