What do I Do when my iPhone says "iPhone Unavailable"?

It is important to understand why this message is appearing, so that it can be avoided in the future. The phone is Unavailable because the wrong passcode has been entered too many times, so the user is locked out of his / her own phone.

The only way to fix this problem is erase / reset the phone and then set it up again.
