So I have a BlackBerry Curve, it's a great phone, but it seems to be nearly useless for the internet. I've got the "Unlimited" data plan and at most 30MB/Month is used. Since it has this amazing plan of 5GB/Month, why can't I use it with my Macbook Pro as a modem? I suppose the real question should be, do they charge a huge fee for this? If they do, why does it cost MORE money than it already does to use the same data plan I ALREADY have?
