BlackBerry

Hi all, I've just ordered a Pearl (hasn't arrived yet) and I'm trying to figure out what plan I need.....I'll be using the phone on Rogers and I currently have a regular phone plan that I do NOT want to change (my system access fee is only 1.00 instead of 6.95). I'm thinking that if I add a mobile internet plan that I'll be able to access data. I'm not to concerned with Email. But the Rogers guys say that it won't work.

Can anyone tell me for sure if it'll work with a regular phone plan plus mobile internet?
