I just plug it into the USB port on my laptop, install some software and I can get online! Since I'm on an unlimited data plan, I can get wireless internet wherever I get cell phone coverage! X-D
The instructions are posted here.
No, I'm not going to do what Kevin does on Fansview. (He uses the Sprint Vision for wireless internet at cons.)
But it's a nice geeky feature to have. :D I need to find a good coverage area and benchmark to see how fast this baby is. ;-)
