For a good one year, ever since the facebook controversy regarding the burning of the Quran hit Pakistan, internet browsing has been significantly restricted on Blackberry devices under the orders of the Lahore High Court and subsequently conveyed to all telco’s via Pakistan Telecommunication Authority. Other cell phone users enjoy unrestricted access to most websites since they rely on simple GPRS connections which can be easily monitored and controlled but Blackberry users face the brunt of the impact of these restrictions since their devices are connected online via a secure tunnel connection to Singapore easily bypassing any government enforced censorship.
My personal position is that any blasphemous / illegal (including porn) content should not be viewed, those individual who seek such content do so on their own free will and they alone are responsible and will be answerable to Allah. Condemning an entire population for something they have no interest in, is unfortunate, and such blanket censorships only become a source of inconvenience.
Most of Pakistani Blackberry users subscribe to Blackberry Internet Services (BIS) which is the simplest form of blackberry service the services and tools are controlled to a great extent by the Telco themselves, one way to bypass all the censorship hoopla is to subscribe to Blackberry Enterprise Server,
