If my laptop has bluetooth, and I connect it to my iphone, does it use my data?

Depending on where I am I don't have wifi connection, but my laptop is able to connect to things with Bluetooth. If I connect it to my iPhone, is it going to use my 3G? Is my phone bill going to skyrocket? This laptop was given to me so I never even knew you could connect a laptop to a phone, so any kind of info would be appreciated!
Thanks
I'd use it for internet access.

I don't know how you will connect it, as the answer depends on HOW you connect it. As data conduit? (i.e. use Internet on phone) As file transfer? (send contacts and files to PC and vice versa) As audio passthru? (i.e. take calls on PC instead of phone)...
