I was using wifi once, when it suddenly turned off. The "switch" to turn it back on in settings is kindof whiter and I physically can't turn it back on. Please Help!
iOS: Wi-Fi or Bluetooth settings grayed out or dim
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

restore as new, if it still wont let you turn it on, the wi fi chip has gone bad.
I have restored it and nothing new has happened except for my iPOD being wiped clean
