Touch ID and passcode issues on iPhone 5S?

I bought a new iPhone 5s three weeks ago. It was brand new in the box, with the original clear wrapper still intact. I bought it from a friend who's parents both bought her one (her parents don't speak, but she thought they would come to an arrangement about who was buying it. Clearly not).

Anyway, everything was working fine until I tried to set up a new finger print in settings. It let me, but then the phone froze and went back to the home screen, as if it wasn't responding. Since then, every time I try to go into the touch id and passlock settings, the phone freezes and the only thing that works are the slide up and down screens. I have to continuously press random things on the slide up and then go back and press cancel as fast as i can, only then will it will go into the touch ID settings. It's fairly annoying, and the phone constantly stops responding, logs out of game centre, and lags until i power it off and back on again.

I'm currently running IOS 7.1.2.

Has anyone else got any problems like this or have i got a faulty phone?

Taking photos of photos = copyright infringement?

I want to post multiple images of movies, tv shows, and youtube videos to my instagram. The images are of repetitive graphic themes that I find within the various media types. For instance: the "oh sh*t!" face on multiple characters from multiple movies. These images would be pictures that I took with my iphone- they would not be screen grabs or anything other than me aiming my camera's phone at a portion of the paused movie or tv show on my computer screen. Am at I major risk of copyright infringement if I post these to my instagram?

IOS 7.1 Jailbreak Untethered?

So, I just learned that iOS 7.1 is now jailbreakable untethered. The tool was called Pangu and it's good for pretty much every device that can do iOS 7. My question is if I have to jailbreak my iphone if it's already tether jailbroken on iOS 7.1 by the geeksn0w tool or can I just download the untethering package that is used by the Pangu tool… Can anybody tell me how I can convert my tethered to untethered? I tried searching on Google but every entry just leads to an explanation of the difference between tethered and untethered. I'd rather be able to just download a package rather than install a program on my computer and re-jailbreak my iphone but I don't know what package to look for.

What is taking up so much space on my iphone? - 2

My phone has 8.0 gigabytes of "other." I've googled what it could be and deleted a few things, but it made no difference. It is taking up Way too much room on my phone… What else could it be? How do I manage it? I think it's one of two really large things taking up all the room, because I've deleted call history, email history, and things like that.

Illegal to sell faulty iPhones?

Someone I know recently purchased a phone from a guy online through a Craigslist type page for $200. The phone wouldn't activate. US Cellular told him that they frequently get "Frankenstein" phones purchased from him, which are basically phones being made from spare parts. Less than half activate and these people lose their money. My friend tried to get his money back after only having the phone for about 12 hours but the guy is insisting on a civil lawsuit. He advertised the phone with no issues and insists that it hasn't been tampered with but the screws on the bottom are missing and US Cellular said it has. What are his options? Has the seller broken any laws? Do you think my friend has a case in small claims court?

What service should i get for my unlocked original iphone 4?

My boyfriend gave me an unlocked iphone 4. It has no sim card slot. So i can't go through at&t. He originally had a phone through sprint, but then brought the unlocked iphone to sprint through the "bring your own phone" program. He switched the original phone back onto sprint and gave me this. Does this mean it is no longer technically unlocked? Id prefer to not have sprint, but if it is locked onto sprint, now that hes used it through them, can i take it back and turn it on in my name? I know its sort of confusing, but hopefully someone can help me out with this, cause i'm having one hell of a time finding it out myself.
