IPhone 4S doesn't turn on/off Wi-Fi?
I got my iPhone 4S recently. All of a sudden, my iPhone doesn't turn on. I keep pressing the home and power button, but it doesn't power on until I hold both buttons (reboot). Once it finally turns on, the Wi-Fi button is shaded. It says that it's off and I'm not able to turn on the Wi-Fi. I have to reboot the device again for it to work. How come this happens? What can I do to fix it?
