Hopefully this isn't a reposting of an old topic.
I've been searching around and the common problem I've been experiencing since the ZiPhone jailbreak have all been permission and owner related (ie change to 755 or chown to mobile). Can anyone explain why permission and ownership settings have been changed?

I've "chown"ed and "chmod"ed my way out of my safari problem, notes, camera and mail.

I assume there are more and it's just a matter of time, but if anyone else has found more problems and fixes, feel free to post them here.

Thanks for you time and help.
