You can clear out the Address Book data base only without having to do a full wipe.
Back up your BlackBerry and follow KB10167 to clear the Address Book and Address Book - All databases
All the contacts should then be erased off your BlackBerry.
If you synchronized with a desktop application like Outlook or using BIS with Gmail or Yahoo, you can re-sync to add them back.
Let me know how you make out
Thanks! And have a good day
