• You click the Remove user data from current device option in the BlackBerry Administration Service after you connect the

BlackBerry device to the BlackBerry Administration Service. This option deletes all data and applications from the BlackBerry

device even if service books do not exist on the BlackBerry device.

Using IT policy rules to specify when a BlackBerry device must delete device data

You can configure the following IT policy rules to require that a BlackBerry® device that runs BlackBerry® Device Software version

4.5 or later automatically deletes device data after a specific time or during specific conditions.

IT policy rule Description

Secure Wipe Delay After IT Policy

Received

This rule specifies the length of time (in hours) that can elapse after receiving an

IT policy update or an IT administration command that a BlackBerry device deletes

all user data.

Secure Wipe Delay After Lock This rule specifies the length of time (in hours) after a BlackBerry device locks that

the device deletes all user data.

Secure Wipe if Low Battery This rule specifies whether a BlackBerry device deletes all user data if the battery

power level is too low.

For more information, see the BlackBerry Enterprise Server Policy Reference Guide.

Resetting a BlackBerry device to factory default settings

You can use the Reset to Factory Defaults on Wipe IT policy rule to require that a BlackBerry® device reset to the factory default

settings when the BlackBerry device receives the Delete all device data and disable device IT administration command over the

wireless network. When you change the value for the IT policy rule to Yes and send the IT administration command to the

BlackBerry device, the BlackBerry device resets to the factory default settings and permanently deletes all device data. If the

BlackBerry device is running BlackBerry® Device Software versions 5.0 and later, the BlackBerry device also deletes the IT policy

and removes third-party applications.

If the BlackBerry device is running BlackBerry Device Software version 5.0 and later and you change the value for the IT policy

rule to Yes, the BlackBerry device resets to factory default settings when you send the IT administration command, when a user

permanently deletes BlackBerry device data, or when the user exceeds the maximum number of password attempts.

When the BlackBerry device resets to the factory default settings, the BlackBerry device overwrites the BlackBerry device memory.

If you or a user turned on content protection, the BlackBerry device also scrubs the BlackBerry device memory. When the BlackBerry

device scrubs the BlackBerry device memory, it deletes any residual unmapped data.
