Hey Lightingbird, what type of prepaid account you have? I try calling ATT and they said they did not have a unlimited data plan for prepaid. Is it a different plan or is it the MediaNet?
I have a 8700r with a 'pay as you go' plan and 1M of MediaNet. I downloaded and installed the opera browser, setup the APN and still would not connect. I search and tried everything possible, I know I am missing something little.
