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 it just get rid of everything! Can i get it back? I tried turning it off then back on hoping it was just being stupid because sometimes it does that but it comes back after i turn it off then back on.

If you are using mail on your Iphone, notes are automatically connected into your email. The only reason your notes get deleted is if someone deleted it from your email. That's what happened to me before.

My notes just got deleted too… NOT A HAPPY CAMPER. That shoud not be happening. If I don't find a GOOD reason this happened. Time for a new phone

  • Why is all of my new e-mail going into my notes folder instead of my inbox? When I check my inbox on my iphone or from the computer, there are not any new messages. When I go into my e-mail account in yahoo mail, my new e-mails are in my notes folder instead of my inbox. On my iphone, there's not a "notes folder" avaliable for me to view. I did not even realize there was a notes folder until I accessed my yahoo mail through the computer. This is the first time I have had this to happen.
  • Why does my iPhone notes app.delete some notes? Some have been there for over a year others just disappear after a few days. I have not (to my knowledge) done anything differently.
  • Why did some of my recent notes disappear? About 3 or 4 of my most recent notes have completely disappeared from my iPhone. In settings notes in iCloud are turned off. It's really freaking me
  • 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?
