How do I clear out my contacts and calendar on my blackberry curve?

Is it possible to sync my contacts and/or calendar to my Blackberry Curve 8900?

• Is there 3rd party software to do this? I need to have my contacts on my BB when I do not have service to connect to Yahoo! Do I have to import information to Gmail or is there another option?

• Answer:

  no, what you are needing to do is to down load the blackberry desk top manager, you can get this download by going to this link: http://na.blackberry.com/eng/services/desktop/ when you go to set up the sync app set it up to use your yahoo acount, and then you will have all of your contacts synced to your yahoo, and to your blackberry. just remember to take out the nicknames on the yahoo acount if you have any, it will confuse the blackberry device
