iPhone: grayed WiFi button after full restore

iPhone has a grayed out wifi button even after network reset and full OS restore (not jailbroken). Will a hardware failure cause the wifi button to gray out?

wel thats badnews.. forgot.. you need shsh blobs to save it.

anyway.. try to soft reset holding menu + power button...
hold it until it reboot.. then try resetting network again.. then reboot..

if still doesnt work.. then i say (probably) a hardware failure.

Was the iPhone jailbroken in the past?

Then it's very likely you corrupted the baseband NVRAM; if the baseband version no longer matches your IOS version, you'll get exactly that symptom.

You'll probably need to wait for Apple to release a new version of the IOS that rewrites the baseband NVRAM; or, alternatively, re-jailbreak your phone.
