My dad has a sprint card for wireless data and only uses it with his laptop on the weekends. I was thinking that during the week I could use it myself with my ipod touch. I have saw the cradlepoint and d-link routers out there but haven't been able to find one that is battery powered and takes the carbus card he has. If you have saw something similar or have any ideas let me know. I am basically trying to make my own version of mifi for free.
