I've been pointing out for several years that any wireless device could be a potential security risk. Take the venerable Palm, for example. The infrared connection that's available to transfer information is a potential risk.
Forget about the potential for hacking or tricky programming techniques (those are a possiblity, of course), but forget about them. Suppose this: you're at lunch with a salesperson. You need to take a Bio break, and you leave your Palm on the table. While you're gone, the salesperson grabs your Palm and starts a transfer. By the time you're back, they've got your entire contact list.
So it's not too surprising that Blackberry is vulnerable. So, too, is Treo, and all the other devices. All it takes is for someone to get the idea that the data that's available on a device is worth getting. They'll figure out a way.
