IPhone problem? Contacts disappeared?

I was synching my iPhone with my computer and emails and now all my contacts are gone! What do I do? Why did this happen?

The same thing happened to me. Its because you don't have your contacts on your computer so by syncing it the contacts have disappeared. They can fix it tin the store I think. I re-entered mine by hand:/ GOOD LUCK.

  • Whatsapp contacts - if they're onnm contacts am I on theirs? I have the phone number of an old friend stored on my iPhone and they also show on my whatsapp contact list… Does this mean that they still have my phone number stored in their phone and also have whatsapp installed on their phone? The chat thing says they haven't been seen since 28th sept? If they didn't have my number on their phone would they still show as one of my contacts on whatsapp?
  • My contacts keep changing into my parent's contacts? I'm using my Dad's old iPhone 4, so it has all of his data. I cleared out everything that was his but I hate the part where each time my parent's add a new contact to their phone, everything syncs over to my contacts, so I'm scrolling down my list and see a new person I don't know but my parents do. Is there a way to change this?
  • My contacts disappeared from my contact list on the iPhone 5s, randomly. How can I get them back? My contact list somehow erased when it was in my purse. The contacts are still there when I create a text message or search someone to text, but I can't dial out because the contacts from my contact list are gone. My iCloud is still on, so it's not that. Is there a way I can get them back?
  • IPhone photos and contacts problem So I just got an iPhone 4, and my mom has the 4s, and when I take a photo or add a contact on my phone, the photo or contact appears on her phone and vise versa. Does anybody know how to turn this off? It's really annoying.
