I have uploaded a zip file of the Ribbit Air example application I created for people to download and try out.  I did a brief tutorial on the Flex Cookbook regarding SMS Texting and the Ribbit API.  This application includes SMS texting as well as a working phone UI that will make calls via the api.  This is just example code that I wanted to put out for folks to mess around with.

Be sure to visit Ribbit to read their tutorials and register for a developer id so you can work with the examples.

Let me know what you think as well.
