Here's a short quote from the above mentioned article:
"Users have experienced vastly reduced functionality of their iPhones, including, most notably, Wi-Fi and Bluetooth connectivity issues, after downloading iOS updates onto their iPhones.
For example, as alleged herein, the Wi-Fi and Bluetooth connectivity issues experienced by users (the "Wi-Fi/Bluetooth Connectivity Issue" or "Grayed out Issue") appears to be most prevalent to iPhone 4s users who downloaded iOS 7."
