can't connect to wifi?
So I have a 32 gig 3rd gen ipod touch. I cannot connect to any Wi-Fi networks. My airplane mode is off, but the Wi-Fi button underneath it, where you choose your network, is grey and I can't click on it. All it says is "No Wi-Fi." Does anyone know what is wrong with it, and how to fix it? I'd prefer not to have to go to the apple store.
