Can I request a different size SIM card when i'm on a contract with AT&T?

I have an HTC One X and it's badly cracking. I was wondering if I buy an iPhone 5 online for AT&T, if I can request a smaller SIM card since iPhone and HTC phones have different size SIM cards. My contract still has about a year left and I was wondering if it's ok to do so. And I read that it doesn't matter because I'm on a contract not my SIM card so it shoukdnt matter, is this true?

Why does she acts like this?

My cousin comes from a long line of money and a huge family on her dad's side. I have to work for every thing I have and all she has to say is I want or need this and her family is there and gives it to her. She works but only like a day a week I got layed off but shortly found something else but in the moment of being layed off she rubbed it in my face she was working. She went and got an expensive Iphone and I have a nice phone but not an Iphone, I don't have health insurance either because I lost it with my job and my new job doesn't offer it she keeps throwing it up in my face she can go to the doctor any time she needs to. I cry just about every day because she treats me this way. Today she went to the NFL game and called me to tell me that her and her boyfriend were going. She knew I couldn't afford tickets to go but still let me know she was going because her boyfriend mom gave them to her. Why does she treat me this way?

Iphone 5c or 5s-Help? I need to choose in the next few hours?

I'm due to get a new phone, and I can choose an iphone, only I'm really unsure, could someone point out some tips? My thoughts on each:

5C
-Colors make it look young and trendy.
-I actually like the thicker body and the apple cases that go with it.
-people say it has excellent battery life.
-I'm not too sure about the plastic.sure perhaps it's durable, but it doesn't feel premium:/

5S
-Too thin and light, don't like that.
-I love the futuristic feel about the phone.
-TouchID = COOL.
-the appearance of the 5c appeals to me slightly more.
-The A7/M7 make it sound future-proofed-great!
-i like the camera upgrades!

Oh and another question, I've heard a lot about Apples official leather case for 5s, but people don't say if it PROTECTS the phone well! Anyone use Apples case? And is 32GB worth another 100$ ? I'm a keen photographer!
