I've heard of these working on a 360, but only when signing up for a new account (granted, only about 5 people have used this for their 360). I'm not going to sign up for a new account and lose all my stats and acheivements over this. It says on the box that it is 360 compatible, but can it be used to RENEW an Xbox 360 account? I don't want to open it and not be able to return it if it doesn't work.
Thanks in advance for answering to whoever does, I appreciate it.
