Yes, your issue is due to a leftover IT policy. As far as I know, there is no way to remove the firewalls. In order to access data you need a BB data plan. Without a BB data plan, no data. However, as you say it is sometimes possible to access the internet with Opera and a GPRS data plan. However, with the policy in place its very possible you will never be able to access this. The only way to remove all policy is to connect the BB back to a bes and push a new blank policy to it.
