I created the list on my computer using Outlook. It is a master list I created to import of a few blackberries. All the contacts sync ok, except for the group.
I have a few BBs that share the same contact list. Instead of creating them using the BB, I created the whole contact list with groups using MS Oulook. I used desktop manager to import the address book to all my BBs. All the contacts imported ok except for the groups.
