Multiple Desktop Contact List on BB

 Found these wonderful thread about this issue here. I just take the question and answer out for you to read easily.

Q: Somehow when I starting syncing my new Storm, I ended up with 3 Desktop Contact Lists - all the same, all with the title of “Desktop”.  Now when I go to Contacts, I have 3 copies of every entry.  Anyone know how I can delete a contact list individually without resetting the unit ? Thanks.
 A: This is caused when someone moves or re-adds a BB user to the BES without wiping their Blackberry before reactivating. This will create a new contact list each time. To remove it, go to Contacts and click Options. Then type rset, it will pop up with a screen asking if you want to wipe the contacts, select yes through all windows. You can then wirelessly sync or use desktop manager to repopulate contacts.

Actually you don’t have to delete all of them, answer yes to the confirmation questions that mentioned “It’s not Sync wirelessly”,  that will get rid of the duplicated ones.
