I am testing the Kool-Aid by trying a new iPhone. The jury is out on some of the features and functionality, but there is one application that is fabulous: Pandora.
If you have not tried Pandora, which allows you to create your own custom radio stations on the web, you should. You can download the iPhone app here.
Pandora is a great company, run by great folks. And best of all, Pandora and GlobalGiving have teamed up to connect Pandora's huge audience of music lovers with GlobalGiving projects that use music to improve the lives of people around the world.
