My iPhone 4s isn't showing iMessages as read?

All of a sudden my iPhone isn't showing received messages as being read. I've clearly read and replied to them, but my iMessage app is still telling me I have unread messages. It's just going up and up. I tried turning my phone off and on again, but all that did was clear the iMessage history on one of my contacts. The number is now stuck at 34 unread messages.

It's an iPhone 4s and I updated to iOS 7 a while back. This problem just started today - any clues on how to fix this?

Switching from an iPhone 4s to an iPhone 4?

My iphone 5 still won't turn on, charge, reset or recover. What should I do?

Its been 2 days now. My phone had 14% the last time i saw it and that was because the wire was faulty, at least, i think it was as you had to hold it in a certain position to charge. It was a cheap wire i brought from the pound shop for temp as i had lost my apple USB connector. Then suddenly it stopped charging altogether so i just thought that the wire werent working anymore. My phone then wouldnt turn on the next day and i was thinking that maybe i forgot to turn it off the day before and the 14% i had on it wasted during the night and died.
So i take it to college that day and i asked my friend to charge it in her lesson cause she has a iphone 5 too and the wire. After class when i go to her she says she charged it for 30 mins and nothing happened, it didn't even turn on. This is when i started to panic.

I have been reserching all the stuff i should do if this happenes and nothing has worked so far. I tried reset, recovery and plugging into itunes and still nothing, (and yes i'm doing it right i have done reset and recovery before).

I keep thinking that the cheap wire has damaged the phone, or the actuall whole for the lightning wire to connect to the iphone as no wire has worked in it.

what should i do? Its not a contract phone so i can't take it back… And i got the phone at the end of august, so its only been about 2/3 months since i got it and i have not dropped it or got water on it since. The phone was in great condition until this.

:(:(:(.

Added (1). Also, forgot to say: the day before this happened a 'Temperature' warning came up on my nphone saying i can't use it till it cools down… And it was PROPER HOT… Like it could burn your skin… Mabye this had something to do with it? But it was fine after that so i dunno.

My Facebook app keeps crashing? IPhone 5 (iOS7.0.3)?

So I open my Facebook app and it crashes within a second! It's never happened to me before. I once had an issue with the same app. It kept saying no internet connection although my connection was fine. It fixed itself in like an hour or so. So what should I do now? Should I wait for it to fix itself or what?

How to put music not from itunes onto a new computer?

Right so i got a new computer last week. I want to get 1000 of my songs from my old computers itunes library onto my new one. Problem is, these songs aren't from itunes, i downloaded them from youtubemp3.org. The itunes library on my new computer only has 100 or so songs that i have purchased from itunes. When i plug my iphone into it, none of the 1000 songs get synced onto it but only songs that are in that itunes library. This is all very confusing to me and i'm not great with computers please help!
