Yesterday i updated my iPhone to the newest firmware version 2.2.

As i usually do, to avoid restoring from a backup, i take the sms.db, the notes.db and other files from the private\var\mobile\Library folder, keep them safe somewhere and after the firmware update (or rather restore) is performed, i put them back inside using SSH. Now this 2.2 upgrade seemed to work fine until i noticed something.

All my previous notes where there when i opened the Mobile Notes app. And whenever i added something it seemed like it was added fine. But after i closed the app and opened it again no changes whatsoever were made to the notes. At first i thought “set permissions to 777″ but it wasn’t that easy. At least not for me…

Setting them to 777 obviously did not work. I tried a dozed other techniques, got a fresh copy of the MobileNotes.app to install, googled for a long while etc. but nothing could change. Thankfully i found the solution just before i start the restore process once again.

I don’t know how it hit me, but the solution was as easy as changing the “Notes” folder permissions too. I didn’t see anyone mentioning that even though some people have blogged about this problem before.

So if you have the problem remember: change FILE + FOLDER permissions!
