On the heels of a massive ban on Facebook due to some "inappropriate" cartoons, the Pakistan Telecommunication Authority (PTA) has also banned the use of all BlackBerry services "until further notice". In addition, some 450 sites including Twitter and other social networks have been banned by the PTA. All cellular companies in Pakistan have been contacted and asked to stop the provisioning of BlackBerry services until the ban is lifted. This means no data, email or BBM for BlackBerry users on any provider included in the ban in an effort to keep users from accessing the banned sites from their devices. Details are still scarce on when/if service will be restored, but we'll keep you posted on anything we find out. Thanks to everyone that sent this in.
