My wife has been a happy user of her iPhone 4s for more than a year. Until tonight, that is.
Her iPhone was updated to iOS 7 some weeks ago, this evening she accepted the phone’s request to update to 7.03. That’s when it started: after the update all network activity seemed to be quite slow. I looked at the phone an saw that the WiFi button was greyed out and would not allow me to enable WiFi!
Summary: an official Apple iOS update will kill the hardware of your iPhone, and Apple wants you to pay to fix what they broke.
Anybody else affected?
