In normal case, your iPhone should work properly after jailbreak. However, in some rare cases, you may encounter some unexpected problems. Other than the YouTube issue after blackra1n jailbreak, here is another problem reported by one of the readers:
“I get to fix the youTube problem. but the Notes app is not working. Everytime I write a new note and click done, the app closes without saving my note. Is there a patch to fix this?”
Yes, there is a fix for that.
If you experience this problem after jailbreak, the database of the Notes application is probably crashed or corrupted. To repair the Notes database, follow the below procedures to fix it:
1. Go to Cydia and install “MobileTerminal”

2. After installation, go back to iPhone home screen and launch “Terminal” app.
3. In the Terminal, key in “cd /private/var/mobile/Library/Notes” and hit “Return”. Then type in “rm notes.db” and hit “Return” to delete the corrupted database.

4. Click Home button to go back to home screen and restart your iPhone (i.e. Power it off and Turn it on again)
After reboot, iPhone will automatically generate a new database file (i.e. notes.db) for the Notes app. Now, launch the Notes app again and write a new note. This time, you should be able to save your note.

Another way is to connect to your iPhone via Cyberduck and delete the file:
notes.db
It is located inside a folder here: private/var/mobile/Library/Notes
@POKEKAT, thanks for your tip. I just think using mobile terminal is an easier way for those who do not know SSH.
I had the same kind of problem with my iphone, but with text messages – when i receive them, i can only look at them when they appear as new on the main screen, when i open the message, it’s gone. And also whenever i send new text messages, they disappear after sending. Can i repair that in some similar way?
@helen, you can do the same for SMS. But the path is /private/var/mobile/Library/SMS. You can then delete the “sms.db”.
now notes can not be started at all ((

It worked for me.Thanks a million.
Dear Simon,
When I type in rm notes.db it asks “do you want to remove write protected notes.db” I gave y and pressed return.
I then says “cannot remove notes.db permission denied’
What should I do?
Alex
