What will happen to my iPhone 5 if it breaks now?

OK, last year I got an iPhone 5 (no android fanboys please) and love it. I live in the UK and am on Contract with EE. (with 4G). I was wondering It';s insured so in case it breaks I'll get sent a new one.
Will I still receive an iPhone 5, after it's been discontinued by Apple following the launch of the 5C and 5S? I don't need an upgrade, I'm just confused! Please help.

(Remember, UK).

Added (1). Yes, just to be clear, they aren't making iPhone 5 anymore.

Is it a good idea to go to apple for something other than buying an iPhone 5S today?

I bought an iPhone less than 14 days ago so I want to return it and get a 5S but I figure so many people will be in line and I don't know how long returns take. I don't want to be there for a long time returning it. I think it'd be rude for everyone else waiting in line. But then again I don't want to wait and then if the iPhones run out I won't be able to return this one or I'll have to go without a phone until I they restock on 5S iPhones.

Should I just go anyways? Does apple take too long when you make a return or will I be able to quickly return this phone and hopefully get the 5S without too much hustle? How long does apple usually take to restock on phones? Like if they run out today will they have more phones tomorrow? Next week?

It's my first time with an iPhone so I've never been to a store on opening day.

IPHONE 4 SCREEN IS TURNED ON BUT BLACK SCREEN?

I updated it to the ios7 update on the 18th and last night i was checking instagram and the screen just went white. I left it over night and it was black in the morning so I plugged it into the charger. I know its on because my alarm was going off but the screen is still black. Please Help I NEED MY PHONE TO WORK. I don't have an apple store near me either.

Should I upgrade my iPhone 3GS to the 5C or 5S?

I live in the UK by the way.
I currently have an iPhone 3GS, which I love, but I'm giving it to my mum because she needs a phone. Plus it's simple for her to use, haha.
Anyway, I really don't know whether to get the 5S or 5C. I was thinking about getting the 5C as it is cheaper, however I'm worried about using it as it is such a big leap from 3GS! I'm not sure? I have compared the specs for both and they both look fine to me. Decisions, decisions!

By the way, I'm not getting one because they are "on-trend", it's because I like Apple phones, they work well for me. Plus I'm not the kind of person to buy mobiles every single year, I've had my 3GS for almost 4 years now.

Thanks.

Why did IOS 7 take up all the space on my iPhone?

I updated it last night, and it was 2.8 before updating. After, and as of right now it's 6.3 GB. What happened! It's saying I need to update again but I don't have enough room to now! I even deleted most of my apps

Do I get the IPhone 4S vs 5C?

I have been given the choice of the two iPhones, but I'm struggling to come to a decision. The iPhone 4S is 200 dollars cheaper outright compared to the iPhone 5C. However, the iPhone 4S probably won't see another iOS update unlike the iPhone 5C. I also like the looks of the 5C, but I was wondering if someone could help me decide. Is to worth the extra $200 dollars, or should I just go cheap?
