If you had a backup, in either iTunes or iCloud, you can restore from that backup and go back to that date. This can help you get some of it back, but most people are too forgetful or lazy to actually do backups regularly until it's too late and they lose data.

And by the way, a backup to iCloud is different than the push function that iCloud also provides. It's two separate sets of data.

  • My iPhone deleted all my notes. Can I get them back? I added a new email, after having a problem with the same one and I deleted it. After I added it back, all my notes were gone. I thought it was a glitch so I turned off my phone and then back on again and it was still gone. Can I get them back? I had a lot of important writing in those documents.

  • 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?
