My Iphone is stuck on the Icloud settings? - 2

I can't change the settings at all on my Iphone5. I don't know what I did to it but now whenever I go to settings it's stuck in icloud I think. There's a red button that says delete account.

Do a hard reset by holding the top and bottom buttons at the same time for about 10 secs (or until apple logo shows up), and then letting go of the bottom button until it turns on. You can also back up your phone, restore it (you have to be on a computer with itunes to do this) and then go back to the original backup.
