Log into the game on your mobile, set a character name on the new Tutorial Island character then go into account settings and set a login/password.
Instructions:
Add a login email to Game Center accounts
Then fully log out and you should be good to go with your regular account.
There is a known problem at the moment with iOS stickying the account login to Game Centre and creating a new account if you don't already have a Game Centre RS game.
