See this KB article:  KB26694 How to change the BlackBerry ID on a BlackBerry PlayBook tablet or BlackBerry smartphone
Changing the BlackBerry ID on the BlackBerry PlayBook or BlackBerry 10 smartphone:
In order to change the BlackBerry ID that is associated to the BlackBerry 10 smartphone or a BlackBerry PlayBook tablet, a security wipe will need to be performed.
Warning: Performing the security wipe will result in loss of stored data on the smartphone or tablet. Be sure to create a backup and also transfer files to a computer prior to performing the security wipe.
Note: In this scenario, the backup file will not be able to be restored to the device since it will be using a new BlackBerry ID. For more information, see KB31317.
Prior to performing a security wipe of the smartphone or tablet, transfer files to a computer so the files can then be transferred back to the smartphone or tablet after the security wipe is complete and the new BlackBerry ID is configured. See the following links for information:
KB26068 - How to transfer files to and from the BlackBerry PlayBook tablet and BlackBerry 10 smartphone.
Manually synchronize music files to the BlackBerry 10 smartphone or BlackBerry PlayBook tablet.
Import your contacts and calendar appointments from Microsoft Outlook.
To perform the security wipe:
On the BlackBerry 10 smartphone, see KB33591.
On the BlackBerry PlayBook tablet, see KB27188.
Once the security wipe has been completed, a new BlackBerry ID can be configured on the smartphone or tablet during the initial setup.
