BlackBerry - Security Knowledge Base

What if someone steals a BlackBerry smartphone, changes the software and then returns it?

Each time a BlackBerry smartphone boots up, the Boot ROM checks the authenticity of the Java� Virtual Machine and Operating System. The Java Virtual Machine then checks the integrity of the BlackBerry software. If any of these checks fail, the smartphone doesn�t boot up.

To successfully change the BlackBerry software, an unauthorized user would need to change the Boot ROM, which is non-trivial and requires access to the device hardware. Thus, the device software can�t be changed without access to the hardware. In addition to requiring proprietary knowledge, accessing the hardware leaves behind evidence the smartphone has been tampered with

Say a Russian spy lifts a BB from his CIA counterpart. He may find the information on the device useful. Not everyone uses a BB just to watch youtube.
