I somehow accidentally changed the password on my iPhone and I tried to guess it but now I can't get into it at all, it's locked up. The phone says to plug it into iTunes and reset it from there, but when I plug it into iTunes it says I can't access it because it's locked. So I'm totally stuck. The Apple Store told me to plug it into iTunes, too. It's a total catch-22. What can I do? PLEASE HELP!!
