I can't create a user name and password for my BlackBerry Internet Service account

If you have BlackBerry 7 or later installed on your BlackBerry device, you cannot create a user name and password to log in to your BlackBerry Internet Service account using a browser. Your BlackBerry Internet Service account is associated with the BlackBerry ID that you used to set up your device, therefore you cannot create a user name and password for your account.

You cannot use your BlackBerry ID to log in to your BlackBerry Internet Service account using a browser.
