Why 3million pick the Blackberry

Blackberry - the handheld e-mail device that has become a badge of honour in executive circles - has hooked its three millionth subscriber.

Corporates like Blackberries because users are restricted to what they can do on the device, which is good for support and security. There is a developing market for corporate smart phones which can be "locked-down" and tightly integrated with a companies secure network.
