Check your carrier's webpages for the Blackberry stuff. They should have links to specific software for various connections between Laptops, OS's, etc... I came across mine for AT&T today while poking around. You should have an account for your wireless account that you can check.
hmmm, don't know how I wound up in the business section but check the Communication Manager-
