So, it looks like (to me) that this is an actual supported service from -in my case- Cingular?

We have a number of folks that are looking at a Salesforce.com deployment, and state that the BB integration isn't enough, so they need cellular cards for their laptops. I think this would be a much better solution, considering we're already paying for an unlimited data plan.

The question for us would be is this indeed a supported solution...? If so, then we can offer it to our users instead of setting up a new cellular contract for each person.
