I just got the N900, and i just got the $10 data plan at the store, and i think i am getting 3.5G at while using the N900, but i am not able to go anywhere, it didn't open any website. however, when i tried to edit the connection, it said it's GPRS connection and i am not able to edit it. Any ideas? thanks

where is the place i can change the APN? thanks
