You can sync your BB contacts to Outlook via Bluetooth and then if the other smartphone has the ability to sync to Outlook, you could sync them over to it.
You'd need a Broadcomm chipset Bluetooth capable laptop (my experience anyway) w/latest Broadcomm drivers and then Desktop Manager configured for Bluetooth in the connectivity settings.
I think the OP wants to transfer contacts directly from the BB to another phone via Bluetooth.
If that's what you're looking for, it can't be done. Only way to actually do that would be to save your contacts as a vCard to the Berry and send them via Bluetooth.
Depending on how many contacts you have, that may work out for you. The other phone you're sending to would have to be compatible with vCards as well.
I just sync to the computer then copy the contacts via bt to the next phone. When I got my bb I sent contacts from my motorola flip via bt to the computer then sync bb to computer to get all contacts to the bb.
