If you do upgrade your account online, a GM told you might be able to hasten the process of removing the trial restrictions by changing your password. I had waited a day. Once I changed my password, it was about an hour before the trial restrictions were removed. Changing your password apparently forces the big Blizz machine to update your account somehow where otherwise it may take up to 3 days for it to cycle through if left alone. BTW, this is just theory, don't know for sure. No guarantees. YMMV.
