Resolvr is a compact, easy to use and free as in beer Zeroconf framework for Symbian OS Smartphones. Using Resolvr, you can make your IP networking applications behave in much the same manner you would use Bluetooth. You can advertise and discover services on the local network, and present available services to users using friendly, human readable names.

In simple terms, Zero Configuration Networking is a standardised way of setting up a network without performing any manual configuration. A networked device that implements Zeroconf can obtain its own IP address, assign itself a human readable host name and advertise and discover services available on the local network without any human interaction what so ever.

There is a huge range of application software released that employs Zeroconf technology to vastly improve the user experience for IP networking:

• Apple’s iTunes - A music player application with built in music store. Uses Zeroconf to advertise and discover music on the local network.
• Internet Explorer and Safari - Web browsers. These use Zeroconf to find and create automatic bookmarks for local web sites.
• Skype - VOIP client. Uses zeroconf to discover people you can phone and chat with on the local network.
• Sailing Clicker - Remote control software. Uses zeroconf to discover machines that can be remote controlled.

Resolvr is available for all Symbian OS smartphones running version 9 of the Operating System or above. However, Resolvr is also Open Source and written in such a way that it would be very easy to backport to older version of the OS if you need support for older phones. A version of Resolvr compatible with UIQ 3 Smartphones will be published shortly.
You can download and use Resolvr for free. Resolvr is licensed under the GNU GPL open source license. For any application for which the restrictions of the GPL are inappropriate, there is also commercial licensing available.
