How to activate and unlock my iphone 5c?

I live in Africa and my aunt purchased a locked iphone 5c from the US Based on the model number (A1456), i'm to believe it's that of a sprint carrier.
My aunt was the one to activate and unbox the phone and she had put in a few things i did not like. So when i got it, i decided to format it (big mistake) and now, it's asking for me to put in a sim for activation… This is my problem, i don't have access to a sim from the US, my aunt is no longer around.i'm pretty much stuck.

Also, if i manage to activate it, can i unlock this cdma phone to be used outside the US?

Any help will be appreciated.

What's shows you better a picture or video?

Well, My friend and I took pictures before cheerleading. I look the same as I do in the mirror, and she looked the same as I see her.
Both of the pictures, one was a mirror, other was facing, looked the same only reversed and was taken on a iPhone camera.
Then a girl took a video of me using her iPod. I looked horrible.
My face was long and my skin seemed yellow and greasy. My hair was flat and had no volume to it at all.
I'm considering the facts that maybe her angle was off on the video, and it was really close up to my face.
I was just wondering which I would base myself off of:/

IPhone 4 help over heat and battery

I have an iPhone 4 and this started happening yesterday, I charge my phone like I do every night, I woke up for school, an I noticed on my way to school, my phones percentage battery would drop literally every minute, and my phone gets very hot. This is the second time this happened. The first time, i let it die out and everything and charged it back up to 100% and by the next morning it was fine. But not this time, I don't feel like it's being over charged cause when my phone reaches 100% I remove it from the charger, but I could be wrong. Any help guys?
