This very little Windows Mobile application will let you DELETE all your appointments, contacts and tasks.
This tweak is very useful when you going to recreate a pairing with a desktop Outlook (or Vista)… if you don’t delete all these things from your mobile device before connecting it to your desktop, all the things will be merged. Also, if you have the same entries on the mobile and on the desktop, those entries will not be synched after the pairing.
USE THIS APPLICATION VERY CAREFULLY !!!
