I've contacted Apple following this link http://www.apple.com/support/contact/, follow the steps. If your Care Plan has expired click on Exception -> IOS7.
It seems my iPhone 4s had a hardware issue with the WIFI chip. Apple replaced my iPhone without costs and mine had no warranty!
Hope it helps!
I am in Canada. iPhone 4S, iOS 7.0.2.
Experienced the same greyed wifi issue since update.
My phone is out of warranty by more than half a year.
Followed instruction from Apple's knowledge base, all the tricks explained here and in other threads, except the dryer/freezer ones.
Sometimes, immediatly after applying a fix, wifi/bluetooth became enabled, but never more than half an hour.
Yesterday, Oct 5, I followed user Tommeucanyellas recommandation, quoted here.
I chose the right Country, and clicked the following:
iPhone > Service request & Troubleshooting > Restore or update not working as expected.
Then I entered my serial number. Then choose iOS 7 in the next menu.
I chose to schedule a call. The phone rang at the exact scheduled time. Spoke to a first nice and polite representative who asked if I tried the workarounds explained on the Apple knowledge base, as well as backup/restore and reset network settings. Then I've been put on hold for a couple of minutes. When she came back, she transferred me to a senior representative.
The senior representative acknowledged the situation and apologied. Without me asking anything yet, he offered me to make an exception, a free replacement.
To get the new phone, he proposed to
-go to an apple store (this is a 3 hours drive for me)
-I send my phone, when they get it the send a new one.
-They charge my CC, send me a phone, then I have 10 days to send them the faulty one with the box I received my new phone in. Then they undo the CC billing.
I chose the last option of course.
The same day the new phone left the warehouse in PA and is scheduled to arrive at my place by tuesday.
At the end of the conversation I asked if he was aware of the technical issue. He couldnt tell me, but said that was a known issue and some customers were experiencing this.
I must admit I've been pleasantly surprised about the outcome of this issue.
For those not having luck at an AppleStore, I suggest you try this.
Thanks to Tommeucanyellas for bringing this solution out.
