Anthony, Kim and Suganthi have put together a Windows Phone 7 App to track CodeMash 2012 (www.codemash.org) sessions. Version 1.0 is available in the marketplace : CodeMash MarketPlace App Link
Version 1.1 (updates, fixes) is pending certification. We hope this update will be certified in time for codemash but if you have a developer unlocked phone we encourage you to download Version 1.1 which includes some bug fixes and feature adds.
Update -> CodeMash V 1.1 is now available in the marketplace.
