Sorry about late reply.
Yes I have setup the APN as described in various forums for Optus, but apparently you cannot connect with Optus using a generic plan. They say you have to have a BB plan.???
I don't need to get forwarded email, I need to access the web for programs like Worldmate, Gmail, Nav4all to mention a few.
If anybody knows how to do it with Optus, or any other Aust carrier, would love to hear from them.
