Iphone 4s settings is screwed up?

I just got an Iphone 4s today and I was playing around with the settings around the time I got it. I inverted the color, but I wanted to change it back. However, every time I open the settings app it shows me all the settings I can choose to change but when I slide my finger or try to touch one of the options, nothing happens. The settings was working earlier today but now it isn't working. I did not drop it or hit it on anything at all. I did, by the way, update it to IOS 6.0.1 or 6.1.0 or something like that. Can somebody please help me?

1) Restart the phone.
>>Press and hold the top right button of the iPhone (sleep button). Wait for the red (would probably be another colour when inverted, obviously) slider that says "Slide to power off" to appear. Slide it.
>>Wait for about a minute until going to the next step.

2) Press and hold the same button you turned the phone off with to turn it back on. This may take about a minute.

3) Now, go back to Settings --> Accessibility --> Tap the "Invert Colors" slide so it switches to OFF.

  • What settings will it change if I press reset all settings on my iPhone? Also, will this help speed up my iPhone because that's what I've heard. Because my iPhone has been so slow lately and taking like 3-5 minutes to send 1 text. If you know of any other ways that could help speed that up please also let me know that.

  • My iPhone 4's volume is screwed up? About 4 months ago, I put my iPhone in my pocket book with my lipgloss. The lipgloss coated where the sound comes from on the bottom. Then about a month after that my phone was dropped in water. My phone didn't act up, yet when I took a video or listened to a voice mail, the sound was extremely low… Even if it was up all the way. If I play music or watch videos, the sound is perfectly fine… How do I fix this?
