Vonage, a provider of voice and messaging services over broadband networks, has launched 1.2 release of the Vonage Mobile application for Facebook for iPhone, iPod touch, and iPad devices.

The 1.2 upgrade allows users to invite their friends directly from their Apple mobile device to download the Vonage Mobile app, and also enables them to send invitations to device contacts via email or SMS.

The Vonage Mobile application for Facebook enables users to make free mobile calls to all of their Facebook friends who have the app, anywhere in the world, directly from their friends list, with a single touch, the company claims.

The service works over Wi-Fi and 3G networks in most countries.

Vonage senior vice president of product development and information technology Nick Lazzaro said they strive to develop services that enable people to communicate on their own terms, and this is a further evolution of their vision.
