While checking out the DX at V, I met someone who had a question that no one could answer. He has 1500 contacts in his BB. However, the BB OS5 allows filters/groups for the contacts. He has one called "Car" with 12 numbers that he calls often. BB allows the upload/transfer of individual filter/groups to the car so he only has to scroll through those 12 numbers. Can the DX offer the same thing where you can only upload selected contacts, or is there an app for that?
