kan ik met mijn blackberry bold alle contactpersonen in een keer verwijderen?

Via de desktop manager gaat het wel ...


Connect via Blackberry Desktop Manager
From Main Menu, click Backup and Restore
From Backup and Restore, click Advanced

You should get a list of device databases on the right. Select Address Book and click Clear, and then select Address Book - All and click Clear. (If you do the "All" step first, you might not have to do the other one.)
