Iphone just randomly deleted all my contacts?

Tonight all of a sudden my iPhone's contact list was empty! I got ios 7 a few weeks ago. Luckily I had opened conversations with the important contacts so I used those to add them to my list but I don't have all of them! Did anyone else face with problem? I don't have iCloud on for it:/

  • 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.
  • My iPhone randomly deleted All of my pictures and videos? I don't know what to do! I did nothing different. I went into my photos and it said 0 photos and 0 videos yet I had 3,000 photos! Now it's restoring some of them, but it seems to be restoring ones I've deleted a LONG time ago. Why the hell is it doing this? I'm confused. My phones been majorly acting up in general. Maybe it's time for a new phone.
