I've been with someone when they signed up for a virgin mobile account (instore), and the rep specifically asked for a new password - and did not prompt with using the birthdate for example. That was in august last year. That said, I distinctly remember the process being somehow a bit wrong - e.g. having to handwrite the 6 digit PIN on some signup form. Once you've got the initial PIN, you can however change it on the website.
