There are ways to get around the fees.. I get free DUN internet access for my notebook with my Env2 on verizon. You just have to change some system settings in the phone. I'm not sure how to do it on your phones... But.. it CAN be done. If you get an Env2 it's reeeallllyy easy to perform the hack in the system menu.

DUN SOULD ALWAS BE INCLUDED WITH "UNLIMITED DATA".. screw u verizon!
