Check out Jeff Wilcox's blog for a great post introducing the Panorama and Pivot controls for Windows Phone. I'm currently using the Panorama control (yes, one of the advantages to working for Microsoft is early access to stuff that is under development) in a Windows phone application I've been working on, and I don't think you'll be disappointed when these controls are publicly available. Unfortunately, I don't know when that will be, but hopefully soon.
