Internet through GPRS not working

[Guest alx5000]

Hi,

I'm using the latest Shokka9's WM6.5 ROM, and I have a problem when connecting through GPRS (Wifi and ActiveSync internet are OK).

After the phone flawlessly establishes the connection, none of my programs can get any data (Opera will utter its famous "Could not locate remote server").

I have tried: setting the Operator Settings to a different provider, waiting for 30 seconds, and setting it back to Yoigo; setting it to a different provider, soft-resetting, setting it back to Yoigo, and soft-resetting again; creating my own connection with my own modem settings; disabing and re-enabling the connection using NoData...

I'm all out of ideas, and would be glad if someone could enlighten me. Thanks in advance.
