ANDOVER, MA, September 29, 2008— envIO networks today announced commercial deployment of its envIOWorks platform with Bharti-Airtel, India’s
leading mobile services provider. The envIOWorks platform is powering Airtel’s Hello Tunes ManagerTM, available via a free download to Airtel’s 75-plus million
mobile customers.

Hello Tunes Manager builds a social marketplace around Airtel’s Hello Tunes ringback tone service. Users can instantly find out what tune they just heard or review a history of recently-heard tunes, and send ratings, comments and requests to their friends. With Hello Tunes Manager, users can search the Hello Tunes catalog to find the latest choices, receive recommendations from their friends or new tune promotions from the envIOWorks platform.

“Our Hello Tunes service lets our subscribers create and experience a personalized calling experience for their friends – their social community” said
Sanjay Gupta, Chief Marketing Officer- Mobile Services Bharti Airtel. “Music in its various forms, genres strikes a universal chord with mobile users and envIO’s
Hello Tunes ManagerTM fits in with the vision of recognizing and leveraging the power of innovative mobile content as the right catalyst for social marketing. The
service will enrich user experience of Hello Tunes, giving a whole new dimension to the way they engage with near and dear ones. We’re seeing this increase both service usage and content consumption.”

EnvIO and Airtel released the Hello Tunes Manager in a “soft launch” in the second quarter of 2008 and have seen exponential growth in service usage, propelled entirely by the viral effect of social marketing.

“We believe our success at Airtel is an excellent validation of our vision” said Prakash Iyer, Founder and CEO of envIO networks. “Mobile content is inherently social, and mobile users want a social experience around this content. Our platform delivers this – and unleashes the power of social marketing to accelerate discovery and consumption of all types of mobile content.”
