Internet explorer error 403 - forbidden

[LinkinParkmetre]

Hello, i've got a really annoying problem with my omnia...
When an application uses internet explorer, like facebook integration in spb, facebook instant messenger, appstore, internet explorer shows an error 403 forbidden
The screen explains the problem i think...
Does anyone know how to solve this?

Thanks a lot

maybe Try contacing your service provider. may be a restriction there I had this with t-mobile a while back

[denjo]

Go to Start>Settings>Connections>Connections>Advanced>Select Networks
Select ''MY ISP'' in the first dropdown box(you can find name of your connection setting instead of My ISP for eg. ''Airtel GPRS'' if you are airtel user)
and select ''My Work Network'' in the second dropdown box.
