My iPhone just lost all of my contacts and calendar entries, except for 5 contacts that I haven't used in years and actually deleted a few months ago. It also lost my saved player info for at least one game (Infinity Blade II).

I didn't change anything or do anything to my phone; it just suddenly doesn't have any of this information. I still have all my apps, most of which seem to be fine, and I still have my recent calls information, but there are no names associated with the numbers.

What could have caused this and how can I get everything back?

EDIT: I tried restarting my phone. That didn't seem to help. But, here it is, 15 minutes later, and almost everything is back. I'm still missing a couple of contacts and my game profile.

EDIT 2: What I would still like to figure out is what happened. The answers are all focused on backup & restore options. None of them addresses what might have gone wrong or how I can prevent this from happening again in the future, which is the real point of this question.

  • are you syncing ? – Ruskes Jun 27 '14 at 23:00
  • No. I wasn't doing anything. – elixenide Jun 27 '14 at 23:03
  • Do you use iCloud ? – Ruskes Jun 27 '14 at 23:04
  • Yes. My phone prompted me to sign into iCloud a few minutes before this happened. I hit cancel, although it still says I'm signed in. – elixenide Jun 27 '14 at 23:06

Recommend you do this

iOS: Back up and restore your iOS device with iCloud or iTunes


Here is also very nice step by step.

    I'm hesitant to do a restore when (1) I don't know what happened, (2) almost everything seems to be back, and (3) I'm not confident my phone has actually been backing up correctly. – elixenide Jun 27 '14 at 23:41

i just backed up manually and everything came back..

    This answer doesn't provide enough details -- you'll find it's going to attract a lot of downvotes as a result. How did you back up manually? Do you really mean "backed up" or do you mean "restored from a previous backup"? – Ian C. Sep 18 '14 at 17:24
