Itunes says my Iphone is over capacity, yet I have nothing on it?

My phone has 8 GB for storage. And I definitely haven't used it all, but it says I have no more capacity. I then went into itunes and it said I had only used 6GB of the 8GB capacity. Yet it says I'm full and won't let me take any more pictures. At first I even deleted almost all my pictures and deleted almost all of my apps until there were only like 2, yet it still won't let me take any more pictures! Is there some wrong setting or something I need to fix/a glitch?

Recovering group texts from iPhone 4s?

I accidentally deleted my group texts I had with my friends from my iPhone, while looking at my texts. It wasn't just one message, it was the entire group, how can I get it back? I'm not sure if I have my itunes set to backup my iphone? And I know a lot of the texts were from after I last connected my phone to my computer anyway. Is there a way to recover them? For free?

I can't follow anyone on Instagram?

I try following someone and it goes to the green "following" button but then immediately goes back to the blue button "follow"

Got any clue?

How much would a broken iphone 4 sell for?

So the screen is like really smashed on the top half, you can still see the actual screen itself and the phone works properly, but also the light on the back of the phone where the camera is, is also broken and turns on and off randomly… But if you knock it with your knuckles it turns off.
I'm selling it to a friend but don't know how much to sell it for? Any ideas?

Upgrading from iPhone 4 to galaxy s4?

So I have a iPhone 4 and my 2 year contract is now over. Some people have said the galaxy s4 has more features and is better than the iphone 5. Should I stick with apple or get the galaxy s4?

Wi-Fi greyed out and some apps won't work?

I have the iPhone 4S updated to everything most recent. I have looked up this question many times and everything with the Wi-Fi graying out has to so with an update. For me, this is not the case. One day my phone just wasn't registering to my Wi-Fi, so I turned my phone on and off. When my phone came back on, the Wi-Fi button wouldn't turn on. I noticed that with this problem I also can't use a few of my apps like castle story, flixter, and whisper. They all just shut out *** soon as I click them. My phone automatically fixed itself about 3 days ago, but the exact same thing happened again. If anyone has ANY solution that doesn't involve sending the phone back, that would be awesome! (I don't want to send it back to get fixed for 100 dollars when my contract is almost up)

Thank you so much!
