I have iOS 7 and a bug caused it to launch Find My iPhone. It will not allow me to access my phone using my Apple ID and if I plug it into iTunes I can't fix it either. How can I use my phone? I don't think I'll even be able to downgrade, being locked out. The Apple store will not help me because iOS 7 isn't released to the general public yet.
IOS 7 locked out due to Find My iPhone bug?

You need to register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and they literally registered my 4S instantly.
