My iPhone is deleting my notes?

I'm having this problem where I will write down notes and it'll be deleted. It's happened in the past where it has only deleted one note so it wasn't that big of a deal. It deleted all but two of my notes. I don't have notes synced up anywhere else, I have an iPhone 3, and no other web links are helping me. Is there anyway I can get these notes back and how do I make it stop deleting?

Try restoring your phone

If i restore will it delete my pics?
