Weird problem here, my Notes application cannot find the notes I've written, it's like they were auto-deleted. The first time it happened I thought maybe I exited without pressing done, thinking maybe that saves it. But it's happened to me several times. I write a note, press done, exit out of the program. Open up the program and the note is still there, but after a day or 2 it's just completely gone. I'm not even syncing it or anything. This is on a ip4 with 4.02 and no JB.
