My iphone 5 is disabled and i don't know the code to unlock it?

My dad bought me an iphone 5 from his friend, but his friend doesn't know the code to unlock it, nor does he know the itunes account to restore it. I typed in multiple passwords like an idiot to try an unlock it but now it's disable, and it says to connect it to itunes. Please tell me how to get it unlocked!

Is someone using my internet?

I was watching videos on my Iphone then I notices a button at the right bottom corner, here is what it said;

Iphone
Andrew's Macbook

I noticed that there's no Andrew in my family. What does this mean? Is someone using my internet? If so what should I do?

No idea what I want for christmas?

Ok I have a massive family & everything I've came up with my mam says she will get it, I don't want her to as I've got no ideas for others but she always has spent quite a lot on me

so I came up with:
bath products
perfume
pjs
clothes
make up & brushes
hair products
ugg boots
underwear
accessories

can people help me as to what I could ask for, I'm 18, a girly girl, don't really drink alcohol or eat chocolate/sweets, have an iPhone, iPad & laptop, love pink, love sparkly things, don't buy CDs as can get music on phone, not a fan of watching loads of films but I do like my soaps, xfactor & I'm a celebrity, I have a pandora bracelet, like unique little gifts, love getting nails & lashes done

thanks

Added (1). I do not want anything, I buy my own things but people are asking me what I want as they've no idea what to get me I have said nothing save your money but yet they keep asking, although I don't want anything they want an answer so saying nothing etc isn't working so I'd appreciate if people could give me ideas (nothing expensive) as for those saying donate to charity etc that's fair enough but my family wants to buy something for me, nothing wrong with that so just please do the helpful thing and give me some suggestions

Is a 16GB iPhone 5C enough storage for someone who?

I will be mainly using the iPhone for email, messaging, calls, and photo/video. A few apps (pandora, candy crush, instagram). I will also be using the internet (chrome or safari) and maybe some news apps (flipboard, weather, rottentomatoes)

I will NOT be watching movies or tv shows. Or reading books on there.

will 16GB be enough? Any tricks for decreasing the amount of memory being used up?

How to edit my CoD: Ghosts Clan with a PC?

My iPhone has very recently broken, and I can't get the app for the video game. From what I have seen, you do much of your clan editing using the app. Like I said though, I can't get the app and need an alternative.

I do not think that Call of Duty would simply assume everyone had an iPhone, (even if, at times, it seems that way) but I have not been able to find ANY alternatives. If anyone could provide a solution, i would be ever so grateful.

Note: I know that you can make a clan in-game, but it does not seem to allow you to alter it in any way. So please do not say "Oh, just make the clan on the game!" This would not be helpful at all.

Why has my iPhone deleted photos?

My iPhone is only showing 143 photos in my photo stream now, when beforehand it has shown all 991 that are showing on my iPad in the same photo stream. I don't understand why this has suddenly happened and would like to be able to get the photos back if possible… Does anyone know how to do this? I'd prefer not to create a new photo stream and transfer them all into that from the iPad but if needs be I will.
