Tethering a Blackberry Curve 9300 on Virgin

[shelbinator]

Hey,

I'm a lucky girl and got given a blackberry by my parents (I have to help with payments of course) and I would like to know how to tether my blackberry to my laptop as modem/use my phones internet on my laptop. I'm on the latest version of windows if that helps

I have got as far as going into blackberry desktop and attempting to set up a custom profile. However I do not to know what to fill in the form with. I tried ringing Virgin and I got rude customer service and got bounced back and force, got shouted at by a very rude man for not remembering my information quickly enough and hung up on! Note: I was polite, even to the shouting man! D:

Anybody who could please help me would have my gratitude. I want to use my laptop at school so I can do my assignments on it during my free periods. The school internet and computers are rubbish it would be so much easier to use my laptop!
