Vodafone GPRS worked for on N900?

I tried using GPRS in my N900 and had setup the connection point. When I connected to 'Vodafone Live', IP is being assigned to the device, but not able to access the internet. I tried enabling proxy (some proxy details are automatically made available in the advance tab of the gprs connection). Once I enable the proxy I m able to surf the net.

But the problem is applications like Pidgin, Witter, Email are not working (may be they are not taking the proxy settings)...

Is Vodafone live connection worked out of box for you or have u done any tricks... Please help!
