IPod Touch Authenticator

So, I downloaded the iPod and iPhone mobile blizzard authenticator and it was working just fine until I loaded the app and it killed my iPod. I couldn't do anything with it, I had to put it in recovery mode and restore it back to factory settings. Now, after that, I can't login because the authenticator is still on my account but I can't use the iPod to get a code.

I'm locked out of my own account and would rather not wait until business hours to play again.
