Can I use my BlackBerry ID on multiple devices?
Yes, you should sign in on all your BlackBerry devices using the same BlackBerry ID. For example, you can sign in to your BlackBerry smartphone and your BlackBerry PlayBook tablet using the same BlackBerry ID.
If you already have a BlackBerry ID, there's no need to create a new one on a new device. You should also sign in using your existing BlackBerry ID when you switch to a new device.
