Aside from tracking the radio signals transmitted by a BlackBerry, what about the actual information being sent? How secure is that?
Pescatore said RIM has in the past built BlackBerry devices for certain customers that include software and hardware to add high-level encryption.

With such end-to-end encryption, which relies on the Advanced Encryption Standard 256, it would be hard to imagine “even a foreign power throwing huge computer power to brute force crack that kind of encryption,” he said.
