Wiping out data in Calendar and People? I'd like to test the different solutions available to sync Outlook with Androphones through USB.

To start from a clean state, is there a way to wipe out the contents of Calendar and People, so I don't have to delete each item manually between each try?

Thank you.
Go to Settings, Applications then find the All tab. Scroll down and you will find Calendar Storage and Contact Data. Open each of these and choose clear data.
