I've seen a Blackberry with two Adress Book or Contact List, one Default (Predeterminado) and other with non-existent gmail accounts like user@gmail.com

I can't find any option on BB menu nor Contact List "Settings" (opciones)

So to delete duplicate address book

1. first made a backup of course with Blackberry Desktop Manager, or take a time to copy your important contact data
2. Go to "Address Book" (Libreta de direcciones)
3. Clic BB Button, clic "Settings" (Opciones)
4. Look for the unwanted google account contact list and type with your keys the word "RSET", answer yes until you get only the "Default Address Book" (Predeterminado)

bye
