IPhone not working after manually changing date?

I just changed the date on my iphone (4s with ios7) from 2013 to 2011 to download an emulator onto it. I haven't downloaded the emulator yet, but after I changed the year all of my apps stopped working. Some of them say "Network Error". Why does changing the year cause this to happen? Has this happened to anyone else?

Note: Safari still works for some reason

My iPhone screen randomly shut off?

I have an iPhone 4 and had the newest upgrade for it. I was sending a snapchat and all of the sudden my screen went from top/bottom and faded all the way to the middle and then turned a faint purple. I had just turned my phone on to rely to a snapchat so It wasn't over heating then but now it's super hot and won't turn off and is staying the purple color. It's only 9 months old and I have never dropped it. Any idea what happened or what to do?

Dropped my iPhone 4S in water, LED won't turn off

So i just recently dropped my iPhone 4S in the toilet. I dried it off as fast as I could and it seemed to work fine. Then the keyboard letters were being weird, only some would show up. I turned it off then back on, the keyboard was fine but then the home button started to fail. Now, the LED light does not turn off even if my phone is turned off. My camera is fogged and full of water, there's a water stain under my screen, my sound does not work and my home button is useless. I can't get to my homescreen without powering off. I've read many blogs/questions/answers about this and everyone says to put it in rice. I have it sitting in rice at the moment but I'm concerned about my LED light, no one else seems to have this problem. Is there any possible way to get my LED light to turn off?
Thank you so much.
And sorry this is so long. I'd gladly answer any of your questions in return.

Fedex Claim denied, what can i do?

I ordered an ipone5s from Verizon. I missed the first attempt that fedex tried to deliver, so I called and told them to hold it, and i went and picked it up the next day. Then i drove to work, and decided to open the package there, and all the accessories were inside the normally sealed fedex box, except my phone. However, the iphone box was not sealed (which is why I don't think Verizon couldve done this, because if Fedex received an unsealed iphone box they wouldnt just put it in the package) I contacted both Verizon and Fedex, and Fedex emailed me a claim form which i filled out and sent back to them. They told me they will contact me in 5-7 days but they didn't. 9 days later i decided to call them, and they notified me that my claim was denied, because there's no evidence. I don't understand how anyone would ever have evidence in this situation, because no one ever opens their package in front of the fedex worker. I ordered my phone right when it came out so i can be one of the first to have it, but now i have to wait another 2-3 months, because its out of stock. I bought it with an upgrade price, which came out to be about $288 with the upgrade fee and tax included. On the claim form, I asked for the full retail price of the phone back ($649.99) because if I tried buying the phone again, they won't give it to me with the upgrade price anymore. Also, my workplace has cameras, and I'm sure if I ask my boss he can get me the video of me opening my package and seeing that my phone isn't inside, I don't know if this will help. Now, i'm all out of options and stuck with an old cracked Iphone4, and I really need some help figuring out what I can do to get at least the $288 back, if not the full retail price of the phone. Any help or suggestions will be greatly appreciated!

IPhone 5 is broken. What would I get with my insurance?

When I was getting my phone out of my pocket, it fell into the side of the chair. It got stuck in the side, and as I was opening up my recliner to see if it was under the chair, it was not there. I found out it was stuck in the side. After I got my phone, the right side it partially bent, but the screen isn't cracked. I know I'll be getting a new phone. I have Sprint, but I'm just wondering what I'll get since the 5 is discontinued. Will I get another 5 or a 5c or 5s. By the way, I know I'll have to pay the hundred dollar deductible. Thanks in advanced!

Added (1). My situation is that I have insurance, I pay $100 no matter what. I'm just wondering what I'll get since the 5 is discontinued.

Should I return my 16g S4 for a 32g?

I've recently upgraded to a Samsung Galaxy S4. I initially ordered the 16G version over the 32G trying to save a few dollars. But, now I find that I may of wanted that extra 16Gs just for the simple fact that I want to get the most out of my upgrade (considering I can only upgrade every two years) and also, with my previous phone, I only had 8Gs of memory (iphone 4, which couldn't be expanded) and I found that to be too little (I hear that the 16G S4 has essentially 8 or 9Gs because the OS takes up much of the storage).

Now, I've heard that you can buy an SD card and upgrade the 16g S4's memory, but I'm not sure if that'll solve all the problems (As I heard that there are some apps and such that can't be saved via an SD Card)

So my question is, should I go through the trouble of trying to switch my 16g phone for a 32g (I would have to return the 16G and pay a restock fee, etc)? Or should I just stick with the 16g and buy an SD card should I need anymore memory? Also, does the 32G perform better than the 16G? (I would assume not, since the only difference is the memory, but it never hurts to ask)
