Many people have asked for the source code of the new version of Salesbuilder that includes Ribbit (phone service) integration, an offline calendar (using the ILog component), and the KapIT visualizer component.
You can now download the source code here.
As a reminder, you can watch a screencast showing the key features of the application here (go full screen for a better viewing experience. Also make sure HD is on).
You must create a Ribbit developer account (free) to be able to use the phone service. Once you have a Ribbit account, click the Options menu item in Salesbuilder and enter your Ribbit user id and password.
You will also need to install the ILog swc if you want to compile the application.
