Can blackberry phones be traced

no. it is possible but the only people with software accurate enough are the police and they wont track your phone just because its stolen.

police will only track your phone if its an emergancy (or something really serious)

they wont track it if it's been stolen or lost because so many people would ask them, or report phones stolen when they've just lost them.

dont pay for ANY online services regarding this as they wont work.
