I have cingular and I am really confused how it works. I see that you can either buy a card, stick your sim into it and either plug it into your laptop or into a router and have internet access. Clearly you'd want to pony up for unlimmited data.
Does anyone do this? What are the differences between the different cards out there? How fast is it? How much does it cost on top of your regular cell bill?
