IPhone Wi-Fi Toggle Greyed out?

Hey guys so my Wi-Fi button on my iPhone 4s is greyed out so I can't turn Wi-Fi on. I updated my iPhone to ios 6 quite a while ago and this just happened today. What is a solution to this? I have already tried resetting Network Settings.
Also, I have never entered a Restrictions Passcode and I have never turned it on before, but it is telling me to enter a passcode anyway, How can I reset the passcode or somehow get past it and turn it off?
Thanks.

Added (1). I got this iPhone in December of 2011, so it doesn't have the warranty thing anymore.

What are some of the differences between the iPhone 4 and 4S?

I've been thinking of getting a smartphone for quite a while now.
My mind's been set on an iPhone. I'm not getting a 5 because it's new, I hear there's hardly any difference between that and 4S and it's expensive too.
My mum found a good deal on the iPhone 4, half the price of a 4S. I've been thinking about it, but to furrther help me in this decision, what are some of the differences?

I had my iPhone stolen, need opinions?

So while I was at 7/11, I must have got money out and put my phone on the counter and forgot about it. Because when I got into my car, I checked my pockets and my phone was gone. Anyway, I then tracked it off my MacBook. The first location there was 3 guys all smoking in the garage. And by hearing there story they all look innocent. So then I totally forgot I could look at the satellite instead of just a map on my gps off my dads iPhone. So I then located the exact house where my phone was at. When I parked outside that house. There was a little kid, leaning on a car and he or she asked what am I doing? I said I want my phone back. There was a guilty silence for about 3 seconds and I then knew this is where my phone is at. He said he would call his dad or whatever. I walked in the garage and just stood there. All of a sudden the guy calls my dads phone and then walks out with my phone in his hand. And he said he found it and was trying to give it back. Looking through my phone, he went and deleted almost all my apps and all my pictures and contacts. The time I was hunting him down, he was doing that. Instead of just turning the phone off. He searched on google, "find my iPhone." So I presume he tried to find out if he could turn the tracking off. Anyway, he gave my phone back without a hassle. My question is, should I report this to the police or anything? And what do you think he was thinking through out the whole ordeal? I called my phone many times and played the find my phone sound and he kept turning it off. So I knew someone had it. Anyways, all answers are appreciated, thanks.
