This has been updated for the 2011 Conference on June 3 - 4, 2011.
Unfortunately I messed up when creating the Google Code project and included the year in the project name.

This application for the Android OS V2.1 or higher is for attendees of the CodeStock Developer's Conference in Knoxville, TN.

The Release to Market version is available on the downloads page. downloads page.

If you still have the 2010 edition installed you should receive a notification of available update soon. If you installed one of the preview editions from this web site, please uninstall it first, then install from the Android Market.
