Hi. A family member has a 7100i as a work phone with what I think to be unlimited data coverage. We are planning a vacation and would like to tether the phone to a laptop for internet access. We have the USB cable and can install the software on the computer. What is the process involved in connecting it, and will it cause any additional charges?

Edit: It is a Nextel phone.

you have to use mobishark and its slower than dial up
