Iphone 6 screen colorful lines?

I dropped my phone in gym class a few months back and my screen completely shattered. Now I randomly go to look at my phone and the entire screen glitches and it has these red, blue, orange, black lines all through it. To the point where almost NOTHING is visible. But I still can hear texts coming in, my screen lights up whenever I get a text or notification and when I swipe to attempt to put in my password it goes but eventually turns off. Please Help
I have no money to replace this phone

Added (1). Btw. I have it plugged to my computer and its charging and going completely normal except for the lines like I can't see anything and it's barely responing now

Is apple pretending there's no backdoor to their iPhone?

Several years ago they hired ex cyber security for NSA, admitted to having the possibility of tracking and monitoring iPhones after whistle blowers came out of the woodwork, is this turned down request to a backdoor by the Feds a hoax to have us believe that there's no backdoor? How has apple been able to recover repair if there was lol

Are AT&T contract iPhone 6s plus unlocked?

We just got an "on contract" AT&T iPhone 6s plus phone (through our family business account) a few months ago. We want to know if when we're traveling to Asia and Europe, is the phone already unlocked? Can we just use a prepaid sim for the country we visit? How can we find out. My wife's friend told her that "All US phones sold in the last 2 years are always unlocked." Is this true? If it is locked, how can we get it unlocked, if we're still "on-contract"?

I'm home sick today, what should I do to make time fly-by?

I'm home sick from school today. My parents said I can't use the PS3. But, I have backups: iPod Touch 5th Gen (I bought with my own money), iPhone 4S, Acer Chromebook C720, Kindle Fire HD (I barely use that), DVD's, TV in my room (I bought with my own money) and the TV in the living room. We a TV which is the room where TV is mainly used compared to my sisters and parents rooms. What should I do to kill time today? I would go to school but I have this bad cough and runny nose. What should I do to pass the time? I'm 15, a boy.

IPhone 6 apps continuously waiting?

So I have an iPhone 6 and here recently it won't let me update existing apps or download new apps. New apps gets stuck in "waiting" (where the icon is greyed out and says waiting underneath). I've tried restarting my phone, signing out of My Apple ID and back in, I've reset my network settings, done a service update, I'm on LTE coverage, have 97GB of room left for storage, and haven't been hooked up to Wi-Fi for about a month and a half now ( we just moved and haven't gotten the Internet set up here yet, but we have gone to Starbucks to use their Wi-Fi for system updates and such.)

With updates for apps I have to do them manually, and here lately they don't want to update either (they get stuck at the stop button and won't complete the process).

Any ideas or help please? I'm in sprint network of that helps at all.

My iPhone 5 is broken, constantly shutting off/not turning on and I really need you

So about 4 days ago a pop up kept coming up on my iPhone saying 'Can't Verify Server Identity' Then it would say 'The identity of ''google.com'' can't be verified by Gmail. Review the certificate details to continue.'
After this the entire phone would shut down. For two days the phone would not turn on, id plug it in to charge and the most that would happen would be that the White screen with black apple logo would come on for about 3-4 seconds and then the phone would shut off, I finally got it to turn on yesterday and I completely restored the phone and updated it from iOs8 to the latest iOs9. However, especially when its not plugged in or after a few minutes of using it purple vertical lines cover the screen and then it completely shuts down, unable to turn back on again for several hours AT LEAST. I can't bring this to an apple store as I live nowhere near one! And I also bought this phone second hand last summer. Also to take note, I'm with Vodafone but on the top left of my screen where it usually shows this network, it just says 'Searching…' It also keeps disconnecting from the charger/computer and then completely shuts off, unable to turn back on. I'm so frustrated!
I really need help. Thank you.
ALSO it was jailbroken to being with if that is helpful? But i had it jailbroken last summer and had no problems with that so?
