Mobile Autheticator and a New Phone

There isn't a way to transfer the application to your new phone, Haniko, although I am not entirely familiar with Blackberry phones or your provider. While it may be possible to do such a transfer, it has always been my experience that a new serial number will be generated in this case. If the serial numbers do not match, you will be locked out of the account and will need to contact Account Services for assistance.

It is at your discretion if you wish to remove the authenticator beforehand. Keep in mind that removing the authenticator does jeopardize account security, even in such a short span of time.
