My Verizon iPhone 5cs data won't work?

For the past three days my iPhones data won't work. I cants send or receive text messages and I can't make or receive calls. I also can't use any apps that require internet when I'm not around Wi-Fi. I don't know what to do. Also when I go to "settings" and click on "cellular" my phone will crash, my phone also will just randomly crash. It's having trouble keeping a charge for very long and is really slow. Does anyone knows what's wrong or what to do? Any answers will be very appreciated!

Should I buy an iphone 5s now or wait until iphone 6 come out?

I've read som rumors that the iphone 6 will be 50 dollars more than the 5s (not sure if its true or not)
I just want an iphone with a good front camera and use instagram, watsapp, twitter etc and other stuff
I actually don't really care about the other upgrades that they make to the iphones every year. So what do you guyz think? Is it worth it? Or should I wait
And btw I dun want to spend so much money on something so overpriced. I had a note 2 and now its broken and not working.

My iphone screen went white when I dropped it?

My iphone 4s was dead, so I decided to charge it. I accidentally bumped the cord with my arm and it fell on the hardwood floor. I picked it up and the screen turned completely white with a horizontal line near the bottom! I've dropped my iphone many times before and it was fine, but i'm not sure why this happened! Its not cracked or anything, and when It won't let me turn it to vibrate or anything. My home button and my back camera weren't working before I dropped it, does that have anything to do with it? What do I do?

Swam in the sea with iphone 5

Dad told me to put the phone in my pocket and i listened to him and guess what? I forgot to take it off my pocket and jumped into the sea with and asthethic pose… Then swam for like 5 mins. I remembered that it was in my pocket and hurried to the bay, i dried it with a towel and pressed the home button but it was turned off already even though it was ON before the swim. Tried to turn it on but no response. Left it under the furious sunlight of turkey for like 15 mins, it was hot enough to burn my hands. I kept drying it but no hope. I went home and plugged in the charger but again it gives no response, any thing i can try to fix this myself? Please give an answer with evidential and logical explanation and don't just say 'no.' so that i will know you know what you are doing.
