The V3 comes with a USB cable in the box. YOu can use the motorola tools CD to upload the contacts and sync with outlook. Then just sync blackberry. I also have a V3 and sync it with outlook (although not a clean process, frankly).
I don'tknow if this is another possibility, but can't you just save your contacts to your sim on the V3 and then copy them to the berry? I haven't tried this but I assume it would work.
Good luck. If you no longer have your motorola CD, let me know and I can email you the software.
