Using the microSD media card with more than one BlackBerry device
If the BlackBerry® device user moves the microSD media card to a BlackBerry device that does not use a device password or uses a password that does not successfully decrypt the microSD media card master key, the BlackBerry device prompts the BlackBerry device user to enter the microSD media card password. If the BlackBerry device has a password, the BlackBerry device user can use the prompt to change the microSD media card password to the BlackBerry device password.
