Whenever i try to access the web it says:

"Unable to open PDP Context to the following APN:

blackberry.net

This may be happening because the current selected Browser configuration is not compatible with the current network."

I have no idea what's going on.
i looked at the browser configurations and they looked fine.
then i checked the APN settings and it said
APN:wap.cingular
Username for APN:WAP@CINGULAR.COM (i also tried )
Password for APN:CINGULAR1

so yeah can anyone help?
much appreciated.
