Can't enable WiFi in iOS 7
My wife has an iPhone 4s and upgraded to iOS7 yesterday.
Today, she's unable to turn on wifi. Even if we go into wifi in the system prefrences, it's like it's diabled. It won't toggle.
If I go in via the drawer at the bottom, it allows me to turn on wifi, but it doesn't actually turn it on.
Airplane mode isn't on. I tried to restart the phone and do a hard refresh and nothing helped.
It's connecting to 3G just fine.
