WHY IS MY IPHONE NOT LETTING ME USE Wi-Fi

I'm so angry right now because I'm not trying to use any data, I can't turn on my Wi-Fi because its greyed out meaning I can't turn it on or off it's just grey. What do I do like I'm getting annoyed ever since the iOS 6 update my phones being stupid

Not sure, I haven't updated my iPhone. They want you to get the new one. Most people say they start having problems with their old ones once the new one comes out. Its just their way of marketing.

  • Why is my new iphone 4s not letting me download more that 245 songs? Itunes says that 245 songs are using 11gb space? Thanks… But when I googled to see how many the answer was 3500 songs? I only have 245 and nothing else on there except the apps that come as standard.
  • Why is my itunes app on my iphone not letting me donwload anything? When i try downloading something from the itunes app on my iphone it says download error/ tap to retry. What does that mean i haven't even went over on my memory. Why does it say that and how do i fix it?

  • Why is my iPhone 5 C not letting me download music from Youtube? Note: I really do not want to hear: That's illegal or why don't you just go buy your music. I know its not exactly legal. Anyway. On my old iPod Touch I was always able to download music off of Youtube. I would use the listentoyoutube.com. I tried to get my download to my iPhone library and it said something about it not being correct or something. I don't know. But if anyone would be able to help me it would be greatly appreciated.
