Why won't my restored iPhone 4S accept my Apple ID credentials? I recently had to restore my iPhone 4S (iOS 7) and when I turned it back on and the activation screen came up, it prompted me for my Apple ID credentials. I put in my Apple ID username and password but it says that it's wrong. I tried to change my password, but when I did, and tried the new password, it still doesn't work. 

What should I do? 

I obviously can't even use my phone to make a call.
Try connecting via https://appleid.apple.com/ probably something wrong with your password.

Consider once you have access to the page to check your contact information, add a secondary e-mail etc…

If you still experience problems you should contact an Apple adviser via http://support.apple.com/
