LiveWire Mobile and Virgin Mobile USA Team Up to Deliver Industry First Ringback Playlist

LiveWire Mobile (NASDAQ: NMSS), a global provider of mobile managed personalization services and Virgin Mobile USA (NYSE: VM), a leading provider of wireless services with no annual contracts, today announced an industry first: the Ringback Playlist. This groundbreaking feature enables customers to access pre-selected content channels instead of choosing individual tracks for their ringback tone.

Ringback Playlist allows customers to personalize their cell phones by choosing their favorite music genre, and setting their ringback tones to select tones from a collection of songs in that category. Each time a call comes into a Virgin Mobile USA customer's handset, a different tune from the Ringback Playlist's selected "station" will be heard by the caller. Ringback Playlists will be available by music genre, artist, or trend with additional personalization options that can be set based on the caller, the day of the week or time of day.

Wes Radez, director of mobile content, Virgin Mobile USA, said, "Adding this unique feature is a natural extension of our very popular ringback service and will give our customers the opportunity to share their favorite artists and music with friends, family and colleagues."

Starting August 1, 2008, Virgin Mobile USA customers will be able to choose from 12 different channels that feature five ringback selections each, such as pop, hip-hop, alternative, country, television and movie classics, the Virgin Mobile Festival* channel and additional Ringback Playlists being added continuously.

Virgin Mobile USA's Ringback Playlist will be supported by LiveWire Mobile's Achieve Marketing Team. This group of dedicated mobile marketing professionals will regularly update track selections within the Ringback Playlist and provide specialized campaign support based on continuously collected metrics.

"By adopting this groundbreaking content delivery feature, and backing it with expert support from our Achieve Marketing Service, Virgin Mobile USA is expanding the attraction of its ringback tone business, one of the mobile industry's fastest growing service offerings, " said Joel Hughes, CEO of LiveWire Mobile. "Enabling subscribers to discover stations of pre-selected and highly contextualized ringbacks will drive exploration of additional content and enable Virgin Mobile to deliver a new level of personalization for their subscribers."

Ringback Playlist will be offered to Virign Mobile USA customers for $3.49/month, plus a $1.49 monthly ringback subscription fee.
