My MobileNotes app (the built in Notes app for iPhone) has entered some sort of inconsistent state and is now crashing on startup.

I would like to recover my notes from it (and also get the app working again, but that's secondary). Has anyone seen this, and/or succeeded at recovering their data?

Starting the app gives the following stack trace/crash data:

This question came from our site for professional and enthusiast programmers.

Even if you could, how would you go about fixing a system application? Send Apple a bug report or restore your system. – CodaFi Jul 5 '12 at 15:38
From the crash report, it looks like it's failing on a data corruption issue somewhere in its data model. I should, in theory, be able to fix that, if I can get proper access to the data somehow. – blueberryfields Jul 5 '12 at 15:40
That somehow is the problem. Even if you could get into the store, core data uses a proprietary format which is compiled, making most attempts futile. By the way, your Snipplr link is broken. – CodaFi Jul 5 '12 at 15:43
The link works fine for me. – C0deH4cker Jul 5 '12 at 15:55

Assuming that you are jailbroken, you can access the Notes database at /var/mobile/Library/Notes/notes.sqlite. In this database, the interesting tables are ZNOTE and ZNOTEBODY. The ZNOTE table contains the title of the note (first line you type in the note) and thr short summary shown in the table view, among other things. The ZNOTEBODY table contains the body of the note in HTML format.

Assuming that this database is corrupted, I suggest backing that db up and then deleting it. Apps usually recreate their databases if they don't exist, but not always (hence my statement about making a backup).

If this still doesn't fix your problem, you can try manually editing the database, finding a fresh copy of the db (probably from the respective ipsw), or, if all else fails, restoring. As long as you back up that database, you can still read the notes by looking in the ZNOTEBODY table. Each line is wrapped in a <div> and ends with a <br>.
