Using your BlackBerry ID to switch devices
When you switch to a new BlackBerry device, during setup, you are prompted to enter your BlackBerry
ID username and password. It's important to sign in using the same BlackBerry ID that you used on your
previous device, because many of your apps and settings are associated with your BlackBerry ID.
For example, when you use your existing BlackBerry ID on your new device, you can reinstall apps that
you downloaded on your previous device from the BlackBerry World storefront, if a version of that app
exists for your new device.
