IPhone has deleted all of my apps when I updated to IOS8?

K what's the question

This is why you are supposed to back up your device to a computer before updating, it is not a common problem but it does happen

  • How to Delete all the stored files and data of snapchat through my iphone 5s. Ios8? I tried searching the web but was not able to get the solution to it. My friend sent me some pics through snapchat which i took the screenshot off but later deleted them. It is still somewhere store in my iphone. I deleted the app but still i have those pics store somewhere in my phone. I came to know this when I tried sharing a pic on instagram and I was able to check all these pics i deleted earlier.
  • Updated iPhone iOS 6.0 and it deleted All MY CONTACTS I do not have anything stored on icloud. Now, I do have all my stuff stored to my computer on iTunes, i just tried to restore my iPhone, but my contacts are not there. I'm very frustrated and mad that this happened.
  • Updated iphone 5 to ios8 and lost photos and access to phototstream? Just updated iphone 5 from ios7 to 8 and now can't access all the photos which were on my photostream? The albums still appear in my phone which i created but there are no photos and none of them have backed up onto my computer. Lost some really important photos so does anyone know how i can find them?
  • My itunes says it hasn't updated een though I updated it? I went to update my iphone and it said I had to update my itunes first and restart my computer (i have a macbook.) So I did all that and went to try and update my phone again and it still said I had to update my itunes first so I did it again and it is still not allowing me to update my iphone. It still says I need the latest version of itunes. What am I do wrong!
