My iPhone won't let me use Wi-Fi?

My iPhone won't give me the option to turn on Wi-Fi whenever I go under settings to Wi-Fi it is grey and when I try to click to turn Wi-Fi on it won't let me.
I tried resetting network settings and it didn't do anything
What do you do? My iPhone is up to date on everything

Well in the future don't buy apple products because they suck, I honestly don't know

This is kind of a shot in the dark, but attempt to turn of data and all other methods of reception to your phone. Basically put it on airplane mode. Then go into the settings menu and try to access Wi-Fi that way.

It still won't let me Wi-Fi still gray

  • Windows Movie Maker won't let me use a video I recorded with my iPhone 4? Why not? I open Windows Movie Maker, and I browse through my pictures/videos and it's not there. Every video I have with my webcam is there, but none of my videos with my iPhone is there. And I don't want to upload the video straight from my iphone because I know the quality will end up being terrible. What do I do?

  • Why won't my iPhone let me use my email? I tried to add my email address to my new iPhone earlier. I put it my name, email address and password, but it says,'The username or password for pop3.live.com is incorrect.' (I have no idea what pop3.live.com is) My email address is correct because I have used it for years prior to today, and my password is correct because I checked it on my email on a computer recently and it worked! So why won't it work now?!
  • Virus won't let me use Internet? I'm connected to the internet but can't browse anything. I called Microsoft and did everything the told me. I also called my ISP and did everything they told me. They came to the conclusion that it's a virus but I don't understand how to fix it without the Internet. Please help. I'm using my iPhone on my home Wi-Fi to type this so I defiantly know it's not the Internet connection.
