Can i trade my iPhone 4s for an iPhone 5c?

So i have an iPhone 4s. I was wondering if I could trade my iPhone 4s for an iPhone 5c. I would probably do this at a US cellular store. Please tell me if you think I would be able to, and how I would - what would I ask/tell them.

IPhone 6 contract free is unlocked?

IPhone 6 "contract free" is unlocked?

Added (1). I preordered the iPhone 6 on friday. It said contract free with t-mobile. I've a doubt concerning if that also means is unlocked or not. I'm not planning on using it on USA, I bought it and will receive it in Miami while I'm on vacations but is for use in Colombia.

How to get your old backup from iCloud on iphone 4?

Last time I updated my phone something went wrong. All it showed was a picture to plug it into your computer, so I did and opened up iTunes. Somehow my phone got reformatted, and it asked if I wanted to recover a backup from the iCloud.
I was given three choices but since my family shares the iCloud I didn't know which to choose. They all said iPhone and gave a time and date it was backed up. So I just chose the most recent backup. Which I found out was my Mom's because I started getting everything she had on her phone. I didn't know what to do so I just went with it, deleted everything I didn't need and just downloaded everything I had before.
It's been a couple months now since I've done this, and we're just now realizing that we both are sharing a few apps. It's annoying to both of us but I don't know how to change it back. I also don't want to try fixing it on my own and possibly screw both of our phones up in the process.
So is there a way to get back my old backup before this happened, or is it possible for me to create a brand new backup for my phone so we both stop sharing apps?

Otterbox Symmetry vs Spigen Case Style Armour for iPhone 6?

I'm looking for a pretty case, but also really good protection. Spigen is on amazon for only $13.99 but Otterbox is still $40… Which is better? Is the Otterbox too bulky? Since the 6 is already really big, I don't want anything too bulky.

Shattered iPhone 4S screen fixable?

Three days ago me and my boyfriend got in a fight and he smashed my phone on a stone wall resulting in the screen being completely shattered. The screen itself doesn't work or show any image it's completely blank so I thought it was broken… Until someone tried calling. My phone still rings the screen is just broken. My brother knows someone that can replace the screen for $60 but do you think the screen itself is fixable?
