Due to some unintended sync, I ended up with >4000 contacts in a contact list under BlackBerry which is a problem to deal. I did not want to wipe the device to re-load everything, esp. the e-mail that I need to refer to from time to time. I solved the problem with the help of a post under BlackBerry support: "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." The magically command "rset" is exactly what I need.
