I updated my iPhone and now it has a passcode?

I just updated my iPhone 4s to iOS 1.7.0, and all of the sudden it has a passcode lock. I didn't set this and now I can't get into it!

Is it asking for a 4 digit passcode or an icloud password? Icloud password is your Apple ID password. If it is a 4 digit passcode you will have to restore your phone using itunes on a computer.

  • Updated iTunes and now does not recognize my iPhone? A day or two ago I was prompted to update iTunes which I did. Now when I plug my iPhone into my computer, iTunes does not recognize it. How do I fix? Computer does recognize my iPhone. (Trying to copy a photo from my computer onto my iPhone and instructions I googled said to use iTunes)
  • My itunes says it hasn't updated een though I updated it? I went to update my iphone and it said I had to update my itunes first and restart my computer (i have a macbook.) So I did all that and went to try and update my phone again and it still said I had to update my itunes first so I did it again and it is still not allowing me to update my iphone. It still says I need the latest version of itunes. What am I do wrong!
