I have an 8820 with AT&T. i have a tethering plan and i have been having the same problems. i have the new script for Leopard(which i think is for all BB models in the same script, right?). i get connected and it claims data is being transmitted, but i cannot load a page. after a few minutes, it disconnects then i have to pull the battery to connect again. has ANYONE figured out how to make this work? im tired of paying for a tether plan with at&t and not being able to tether.
