How to get rid of iCloud on iphone?

I'm not quite sure how to say this but I'm getting tired of iCloud sharing my contacts and text and pictures with my family. And I'm getting tired of receiving their texts and their contacts. My contacts is filled with people I don't know and it's really irritating.

Does anyone know how to turn off iCloud or get rid of it?

How to get your iphone4s' music to play?

My iPhone has a ton of my music on it and I have synced with my computer prior to having to get a new iPhone do to a problem. After three days of having the new iPhone and syncing everything back onto it my music no longer plays. If I click in my music it goes through my list of songs or through my albums. The pause button is on so it should be playing but it's like it has a Mind of its own and just scrolls through everything and plays nothing at all.

IPhone 5 and iTunes download

IPhone 5 very poor battery life?

Hi
My parents bought me an iPhone 5 for Christmas and I have found that the battery life on it is very poor. I have had no phone since October after I dropped my BlackBerry in the bath so I was looking forward to this iPhone (I knew I was getting it)
It is losing up to 20% of power in as little as 25 minutes. Although I do text and play music a lot, I don't think it should be losing this much power in such a short amount of time.

I also have an iPod Touch 4th Gen, iPad 1 and iPad 4 and I play a lot of music, use lots of apps and internet on there too (especially iPod) but they don't lose this much power.

When I turned the phone on yesterday, a software update was immediately available, to fix a bug impacting Wi-Fi. So I installed the update and then started to use the phone.

Does anybody else have any problems with the iPhone 5 battery life or is it just me?

The phone is on a pay monthly contract with O2 if this is relevant.
What should I do?

Thanks

Where can I watch Titanic (1997) online free?

Things to consider before buying used iPhone?

I'm going to meet up with this person whose selling his white 4s for $350. I saw his ad online (Kijiji) and he just got it 2 months ago, so that means that there's 10 months of warranty left. He's selling it because he upgraded to a 5. How can I know if the iPhone is in good condition, physically and internally? How would I know if it had water damage or not, or any kind of bad things that he did to it? I don't want to get scammed so what are the things I should consider before buying a used iPhone?

Added (1). Also, how would I know if its a stolen phone or not? It comes with the box and everything but it isn't sealed
