Want to get in on all the iPhone app glory, but with the goodness of Bing?  Now you can, using the Bing iPhone and Mac SDK, available on CodePlex as open source under the Microsoft Public License (MS-PL).  According to a post on the Bing Community blog:

The SDK provides:

* The ability to easily query Bing from within your Cocoa or Cocoa Touch application.

* Perform both synchronous and asynchronous queries.

* Search Bing for Web, Image, Video, News, and Phonebook results.
