You've come to the right place for help ClareK. I can certainly understand how inconvenient this must be for him. Let's get your husband's phone unfrozen so he can go back to enjoying his phone.
Which iPhone does he have? Any damage to the phone? What happens when you try powering the phone off? What steps have you taken to attempt to power the phone off? Is it frozen on a particular screen? Did it freeze when accessing a certain app or function on the phone?
