Why did my iPhone 3GS delete all my contacts?

And I did not back it up on the iCloud. Is there any way I can recover them? Also, all the phone numbers are still on the Recent section, but they are all in number forms; some of them used to be on my contact list before they were wiped out, same way on my Favorites section.

The bigger questions is, WTF IS AN IPHONE 3 lmao. Nah foreal i don't know try getting them back from a back up app

There are two ways to recover iPhone lost contact.

One is using an iPhone data recovery program to recover data directly from iPhone, such as Tenorshare iPhone Data Recovery. The other is recover contact from iTunes, here is the details:

1. Connect the iPhone to the computer with a USB cable.
2. Open iTunes.
3. If you have a new or erased iPhone, iTunes will prompt you to restore from backup.
4. Otherwise, Control-click on your iPhone under DEVICES in the left menu.
5. Select Restore From Backup…
6. Choose the backup you wish to sync and click the Restore button.

  • Why did my iphone delete all of my notes? Saying that i'm pissed off is an understatement. I want to smash the fcking thing! I had passwords and other important things saved in my notes!

  • Why did my iPhone delete all of my calendar entries? Yesterday afternoon, I sync my iPhone to my computer and let it backup. All my dates were there on the phone (while it was plugged in). This morning, I look to see why my phone hadn't alerted me for work. It turns out that all of my entries (except for birthday associated with contacts) have disappeared! Can someone tell me what went wrong and how to get them back?
  • Why did my iPhone delete all my contacts? I picked my iPhone 4 up to reply to a text message, and when I tried to open that message my phone froze and wouldn't open my message, phone, Bing or Google apps. I had to turn the phone off in order for the apps to open, and when they did all of my contacts were gone. What could cause this?
  • Why did iTunes delete all my apps? I plugged my iPhone into the computer to download a song that I had bought. All I did was upload the song to my phone, press eject, and take it out. When I went back to my home screen, all my apps were gone except 5 of them! Why did this happen!
